The Tethered Aerostat Radar System, also known as the EASER system, is an American low-level airborne radar surveillance system which uses aerostats as radio radar platforms. Like other similar systems, this uses a combination of microwave transmitters and receivers for airborne tracking. These measurements allow the monitoring of terrain below and above the aerostat itself. These measurements are essential for the detection and tracking of on-coming aircraft, providing invaluable real-time information to decision makers.
Why Should One Opt For Blimps Instead of Tethered Aerostats?
Because of the inherent sensitivity of the airborne relay, it is often required by law for private aircraft to have their own aerostat system installed and in some cases, the FAA has even regulated the installation of this equipment. It is important for a business to understand the limitations of the equipment when selecting a tethered aerostat system, because while this equipment is designed for low-altitude flights only, it is often required that an airport will mandate that the aircraft have one in case of an emergency or other air emergency. Even if the airport does not have such a requirement, it may be wise to have the equipment installed for reasons beyond emergency reasons, such as to prevent damage to personal property, prevent aircraft from colliding with nearby aircraft, or for monitoring and to assist with rescue efforts.
Some of the most interesting applications of the tethered aerostats and the communications associated with them are the use of this information to control communication between aerial vehicles and on-ground sites. This includes the movement of communication links between the control station and on-ground sites, and between aerial vehicles and at-fly communication links. For example, the communication of the unmanned aerial vehicles may use the information generated by the radars for aerial refueling and route planning. This allows for the rerouting of operations, avoiding certain areas where the vehicle has an accident or other problem. Further, the information can be used to detect and recover the flight path of the unmanned aerial vehicles, saving precious time and preventing further accidents.
