The Sea Cadets is a fantastic youth organisation for young people between the age of 10 and 18. The Corps guides young people towards responsible adulthood by encouraging and developing valuable personal attributes and high standards of conduct using a nautical theme based on the customs of the Royal Navy.
Each individual Sea Cadet Unit is an independent charity, which must be fully self-sufficient in terms of funding, and provide a wide range of activities both water-borne and shore-based.
Occasionally there is a requirement for a GPS repeater system to be deployed in a damp environment such as a mine, tunnel or car park. These locations may not be actually under water, but the atmosphere can be wet or humid; car parks notoriously have water streaming down the interior walls.
Under such conditions, equipment can start to corrode very quickly; especially electronic circuits and connectors inside standard enclosures. Moisture can track its way along cables and seep into the interior until short circuits occur, ultimately resulting in system failure.
To overcome this problem, all the GPS repeater equipment carried by FalTech is now available in water-resistant boxes that comply with the IP67 standard.
Over the last two years, GPS L1 repeater kits, operating at 1.575GHz, have made a real difference to the day-to-day operations of hundreds of companies and organisations.
A GPS repeater inside a fire station ensures that satellite navigation equipment in each appliance has a constant signal when indoors; so that when they leave the station they immediately acquire GPS lock.
Similarly, a repeater inside a police station ensures that all personal radios receive a live GPS signal while indoors. Upon exiting the station the radios immediately start to transmit accurate location data with zero acquisition delay.
A repeater inside an aircraft servicing hangar means that aeroplanes do not need to be taken outside to receive a signal. A GPS repeater system provides a signal over a large floor area – approx. 35M x 35M if the repeater is located 10M above floor level.
Electronics companies from a wide variety of backgrounds find that an indoor GPS signal removes the requirement to take GPS-enabled devices outdoors for testing.
Building on the continuing success of its L1 GPS repeater kits, the FalTech GPS product range has been extended to cover the L2 and GLONASS frequencies.
This is such a great use of technology; an in-vehicle system that alerts the emergency services immediately a collision occurs.
eCall is an initiative developed under the Digital Agenda For Europe banner, with the purpose to bring rapid assistance to motorists involved in a collision anywhere in the European Union.
Each vehicle’s position is noted by a GPS receiver, and if an accident occurs the system transmits vital data across the mobile network to a call centre known as a PSAP – public-safety answering point.
Not only does it send GPS location details, it can also let the operator know if one or more airbags have been deployed, along with impact sensor information.
As soon as the data is received the operator knows the location and severity of the impact and will mobilise the appropriate resources.
Most people have experienced the frustration of not being able to receive a mobile phone signal while indoors; it’s even more irritating when there’s a perfectly usable signal just outside the door.
The situation is usually caused by the structure of the building; the signals just can’t penetrate through the walls. Ironically it’s often modern insulating materials such as foil-backed insulation that prevent the ingress of signal and makes it necessary to go outside in the cold to make a call.
Nowadays of course mobile devices aren’t just phones; they perform a vast range of other functions, some of which rely on the reception of GPS satellite signals which are usually only available outside the building.
