An EPIRB, otherwise known as a Emergency Position Indicating Radio Beacon, is a distress signal beacon used in the event of an emergency. They are most commonly used by search and rescue teams to locate anyone who has triggered it in distress. An example would be a ship which is sinking due to a breached hull, or an aeroplane falling to Earth with failed jet turbines. In the event of an emergency, such as a sinking ship or an airplane crash, the EPIRB transmitter is activated and begins transmitting a continuous radio signal. The way in which an EPIRB works is that it...

A GPS jammer, or jamming device or radio navigation satellite service (RNSS) jammer is most commonly a small, self-contained, transmitter device used block radio signals used for GPS locating. Most commonly they are used to hide the users location by sending radio signals which conflict the same frequencies used by a GPS device. When this signal jamming occurs, the GPS device is unable to determine its position due to the interference. How does a GPS jammer works To understand how a jammer works, it is important to know how GPS works. Firstly, A GPS device receives signals...

GPS tracking devices work in conjunction with GPS tracking software to monitor vehicles & assets in real-time, using location co-ordinates obtained over GPS, and then sent directly to a user, or tracking software which is then accessed by a user. GPS Tracking Devices Telemetry Data Exchange and Collection Telemetric data is sent and receives by a GPS tracker in one of the following ways: The Global Positioning SystemSatellites supply latitude/longitude co-ordinates Diagnostic plug-insOBD diagnostic information such as Engine RPM, VIN number, MPG CANbus Such as Sealtbelts,...

JDAM, otherwise known as Joint Direct Attack Munition, is a guidance kit which turns unguided "dumb bombs" into GPS guided munitions. Bombs which are equipped with JDAM are pecision-guided by an integrated inertial guidance system in conjunction with a GPS receiver. This in turn increases their range to up to 28m. The guidance system used by JDAM was jointly developed by the US Air Force and the US navy, giving the name 'join' within JDAM. When this guidance system is installed onto a bomb, the kit is given a Guided Bomb Unit (GBU) nomenclature.This supercedes the Mark 80 or BLU (Bomb,...
