SOS Alert Application : Fast Help When You Need it 


SOS Alert : Emergency Support

SOS Alert helps lone workers in a crisis. If they feel at risk or need support, they simply select the SOS Alert option on their device Osmile ED1000 . This will immediately open a two-way call with highly trained staff at the Alarm Receiving Centre (ARC). The ARC operates 24/7/365, guaranteeing a response in seconds.



The ARC officer has secure access to the worker’s personal emergency escalation protocol and real-time GPS location. This lets us direct emergency services straight to the worker, bypassing 119 call centers and saving critical time. If there is a false alarm, the worker can simply tell the ARC to stand down.


Virtual buddy

SOS Alert can also be used as a virtual buddy. The ARC operative will stay on the call with a worker, should they feel at risk. For example, if they’re working late at night and are uncomfortable in a poorly lit car park, ARC staff can stay alert as they walk to their vehicle.


Active Listening

The ARC staff use the initial seconds of the call for active listening, in case a vulnerable worker can’t speak freely. Calls are recorded, and the recordings are admissible as evidence in court, for example in case of prosecution for an assault.


Worker Down Application : No-movement and fall alarm

Osmile ED1000 uses the built-in motion sensors in the watch to enable Worker Down. Osmile ED1000 then monitors the movement of the watch and its orientation. If, for example, lone worker after a fall,  and the Osmile ED1000 fall alert is triggered, and the lone worker didn't touch the Osmile ED1000 button to switch it off, then an alarm Worker Down will send to (ARC) to call for help.

The operatives there will access the worker’s GPS location and call the worker’s phone to see if they’re OK. In the event of a false alarm, the worker can simply, switch off the fall alarm or advise the ARC to ‘stand down’. If ARC staff can’t contact the worker via their watch, they will automatically follow the next steps in the person’s individual escalation procedure, and can quickly dispatch emergency services to the worker’s location.


GPS Application : Locate Finding your workers in a crisis

GPS Locate : Pinpoint accuracy

When using Osmile ED1000, the lone worker’s GPS location is reported to the system every ten minutes as standard (although this frequency can be customised), and whenever a SOS Aler or Worker Down Alert is raised.


About GPS

The Global Positioning System (GPS) tracking system uses a network of satellites linked via Osmile ED1000 to the lone worker’s device or app. The network consists of 30 satellites broadcasting radio signals in a permanent near-earth orbit of approximately 20,000 km. Now used widely around the globe, GPS was initially set up for US military navigation. The first satellite in the system, Navstar 1, was launched in 1978.



From any point on the globe, four GPS satellites are visible all the time. At regular intervals, they each transmit the current time and their location. The signals reach your lone working device, and Safe Hub calculates how long the message took to reach you and your distance from the satellite. By overlaying the information from three of the visible satellites, GPS can pinpoint your location. This process is called trilateration.


Customized use

Osmile ED1000 lets us customize the settings for each client to ensure the use of GPS Locate complies with their individual policies and procedures around privacy. So you can choose exactly who can see a worker’s GPS location, and how that information can be used. Each activity performed within Safe Hub is tracked to allow for monitoring and compliance.


Benefit of Lone Worker GPS Watch

1. Reduction of Risk for Lone Workers

2. Reduction of Liability for Employers

3. Call for Emergency Help Immediately

4. Tracking Enables More Effective Administration

5. Fewer Employees Required in the Field



Lone workers

A Lone Worker (LW) is an employee who performs an activity that is carried out in isolation from other workers without close or direct supervision. Such staff may be exposed to risk because there is no-one to assist them and so a risk assessment may be required. Lone workers are now often supported by cloud-based automated monitoring systems and specialised monitoring call centres - often referred to as an 'Alarm Receiving Centre' or 'ARC' in the UK, or 'Emergency Dispatch Center' or 'EDC' in the US.


Examples of lone workers

There are different types of lone workers including:

  1. People working at home such as telecommuters, affiliated marketers, writers
  2. Workers in the energy industry or oil and gas Industry including upstream workers like surveyors, land managers, drillers, and midstream or downstream workers such as refinery workers and drivers
  3. Construction workers
  4. Mobile workers such as traveling salesmen, truck drivers, health visitors, repair technicians
  5. People who work in any type of manufacturing facility
  6. People working outside normal hours such as security guards, cleaners
  7. Utility workers such as meter readers or technicians

Countries with lone worker legislation
The following countries have enacted lone worker legislation:
Canada (Provinces of Alberta, British Columbia, Manitoba, Saskatchewan)
New Zealand
United Kingdom

In Australia
Australia has legislation regarding lone workers and their employers. As of the 1st of January 2014, it has become compulsory for employers to monitor the health and well being of any of their employees working remotely or in isolated conditions. Control measures are now in place to ensure effective communication and worker monitoring are in place as well as access to assistance of emergency services for isolated or remote workers. Regulation 48 from the Managing the Work Environment and Facilities Code of Practice 2011 outlines definitions of isolated and remote workers as well as possible control measures and should be read for more information in regard to this law.'
Guidance Note, Working Alone 2009

In Canada
The definition of a Lone Worker in Canada is someone who is alone at work or when they are on their own; when they cannot be seen or heard by another person. Lone worker regulations are complicated by the fact that there are fourteen jurisdictions – one federal, ten provincial and three territorial. Some of the provinces in Canada have enacted legislation regarding employer’s responsibility towards Lone Workers by having their governments create health and safety legislation. The legislations outline the general rights and responsibilities of the employer, the supervisor and the worker. Ontario, Nova Scotia and Yukon have no lone worker specific regulations.

In New Zealand
Employment New Zealand defines working alone as ‘Working alone is when work is done in a location where the employee can’t physically see or talk to other staff.
The Health and Safety at Work Act 2015, requires employers to maintain regular contact with employees working alone or in isolation, if this is not possible, they should check in with a designated person at regular intervals. The employer must also provide an effective means of getting help quickly in an emergency. 

In Spain
Spain has codified laws governing the protection of lone workers.

Other Application that could use Osmile ED1000 GPS watch for emergency and safety management, such as the following:

Security Guard:

A security guard (also known as a security inspector or security officer, or Protective agent) is a person employed by a government or private party to protect the employing party's assets (property, people, equipment, money, etc.) from a variety of hazards (such as waste, damaged property, unsafe worker behavior, criminal activity such as theft, etc.) by enforcing preventative measures. Security guards do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, looking (either directly, through patrols, or indirectly, by monitoring alarm systems or video surveillance cameras) for signs of crime or other hazards (such as a fire), taking action to minimize damage (such as warning and escorting trespassers off property), and reporting any incidents to their clients and emergency services (such as the police or paramedics), as appropriate. Security guard is a dangerous job, as their safety might be threatened at any time, while enforcing rules and regulations, they definitely need to be back up by the best gps trackers and sos emergency button device, such as Osmile ED1000 GPS watch.

Osmile Lone Worker comes with the option of our 24/7 monitoring, or you can monitor in-house with our APP based platform, giving managers the ability to protect their workers at all times.

What is GPS?
Discover everything you need to know about GPS and how it is used today.
GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronization. 

GPS is everywhere. You can find GPS systems in your car, your smartphone and your watch. GPS helps you get where you are going, from point A to point B. What is GPS? Read this article to learn more about how it works, its history and future advancements.

What is GPS and how does it work?
The Global Positioning System (GPS) is a navigation system using satellites, a receiver and algorithms to synchronize location, velocity and time data for air, sea and land travel.

The satellite system consists of a constellation of 24 satellites in six Earth-centered orbital planes, each with four satellites, orbiting at 13,000 miles (20,000 km) above Earth and traveling at a speed of 8,700 mph(14,000 km/h).

While we only need three satellites to produce a location on earth’s surface, a fourth satellite is often used to validate the information from the other three. The fourth satellite also moves us into the third-dimension and allows us to calculate the altitude of a device.

What are the three elements of GPS?
GPS is made up of three different components, called segments, that work together to provide location information.

The three segments of GPS are:

Space (Satellites) — The satellites circling the Earth, transmitting signals to users on geographical position and time of day.

Ground control — The Control Segment is made up of Earth-based monitor stations, master control stations and ground antenna. Control activities include tracking and operating the satellites in space and monitoring transmissions. There are monitoring stations on almost every continent in the world, including North and South America, Africa, Europe, Asia and Australia.

User equipment — GPS receivers and transmitters including items like watches, smartphones and telematic devices.

How does GPS technology work?
GPS works through a technique called trilateration. Used to calculate location, velocity and elevation, trilateration collects signals from satellites to output location information. It is often mistaken for triangulation, which is used to measure angles, not distances.

Satellites orbiting the earth send signals to be read and interpreted by a GPS device, situated on or near the earth’s surface. To calculate location, a GPS device must be able to read the signal from at least four satellites.

Each satellite in the network circles the earth twice a day, and each satellite sends a unique signal, orbital parameters and time. At any given moment, a GPS device can read the signals from six or more satellites.

A single satellite broadcasts a microwave signal which is picked up by a GPS device and used to calculate the distance from the GPS device to the satellite. Since a GPS device only gives information about the distance from a satellite, a single satellite cannot provide much location information. Satellites do not give off information about angles, so the location of a GPS device could be anywhere on a sphere’s surface area.

When a satellite sends a signal, it creates a circle with a radius measured from the GPS device to the satellite.

When we add a second satellite, it creates a second circle, and the location is narrowed down to one of two points where the circles intersect.

With a third satellite, the device’s location can finally be determined, as the device is at the intersection of all three circles.

That said, we live in a three-dimensional world, which means that each satellite produces a sphere, not a circle. The intersection of three spheres produces two points of intersection, so the point nearest Earth is chosen.

Here is an illustration of satellite ranging:

As a device moves, the radius (distance to the satellite) changes. When the radius changes, new spheres are produced, giving us a new position. We can use that data, combined with the time from the satellite, to determine velocity, calculate the distance to our destination and the ETA.

What are the uses of GPS?
GPS is a powerful and dependable tool for businesses and organizations in many different industries. Surveyors, scientists, pilots, boat captains, first responders, and workers in mining and agriculture, are just some of the people who use GPS on a daily basis for work. They use GPS information for preparing accurate surveys and maps, taking precise time measurements, tracking position or location, and for navigation. GPS works at all times and in almost all weather conditions.

There are five main uses of GPS:
  1. Location — Determining a position.
  2. Navigation — Getting from one location to another.
  3. Tracking — Monitoring object or personal movement.
  4. Mapping — Creating maps of the world. 
  5. Timing — Making it possible to take precise time measurements.

Some specific examples of GPS use cases include:
Emergency Response: During an emergency or natural disaster, first responders use GPS for mapping, following and predicting weather, and keeping track of emergency personnel. In the EU and Russia, the eCall regulation relies on GLONASS technology (a GPS alternative) and telematics to send data to emergency services in the case of a vehicle crash, reducing response time. 

Entertainment: GPS can be incorporated into games and activities like Pokémon Go and Geocaching.

Health and fitness: Smartwatches and wearable technology can track fitness activity (such as running distance) and benchmark it against a similar demographic.

Construction, mining and off-road trucking: From locating equipment, to measuring and improving asset allocation, GPS enables companies to increase return on their assets. 

Transportation: Logistics companies implement telematics systems to improve driver productivity and safety. A truck tracker can be used to support route optimization, fuel efficiency, driver safety and compliance.

Other industries where GPS is used include: agriculture, autonomous vehicles, sales and services, the military, mobile communications, security, and fishing.

How accurate is GPS?
GPS device accuracy depends on many variables, such as the number of satellites available, the ionosphere, the urban environment and more.

Some factors that can hinder GPS accuracy include:
Physical obstructions: Arrival time measurements can be skewed by large masses like mountains, buildings, trees and more.

Atmospheric effects: Ionospheric delays, heavy storm cover and solar storms can all affect GPS devices.
Ephemeris: The orbital model within a satellite could be incorrect or out-of-date, although this is becoming increasingly rare.

Numerical miscalculations: This might be a factor when the device hardware is not designed to specifications.

Artificial interference: These include GPS jamming or spoofs.
Accuracy tends to be higher in open areas with no adjacent tall buildings that can block signals. This effect is known as an urban canyon. When a device is surrounded by large buildings, like in downtown Manhattan or Toronto, the satellite signal is first blocked, and then bounced off a building, where it is finally read by the device. This can result in miscalculations of the satellite distance.

A brief history of GPS
Humans have been practicing navigation for thousands of years using the sun, moon, stars, and later, the sextant. GPS was an advancement of the 20th century made possible by space-age technology.

GPS technology has been used globally throughout history. The launch of Russia’s Sputnik I satellite in 1957 ushered in the possibility of geolocation capabilities and soon after, the U.S. Department of Defense began using it for submarine navigation.

In 1983, the U.S. government made GPS publically available, but still kept control of the available data. It wasn’t until 2000 that companies and the general public gained full access to the use of GPS, eventually paving the way for greater GPS advancement.
