GPS Repeating Explained
The increasing popularity of GNSS – Global Navigation Satellite System (GPS, Glonass, Galileo, Compass, Beidou-2, IRNSS) terminals, systems and services has generated new applications and given rise to expectations that these devices would be able to operate indoors as well. Take a moment to watch the video to learn how GPS Repeaters work.
Typical Use Cases
Within the aviation industry, installing GNSS repeater systems in hangars can amount to huge savings when planes no longer need to be towed out of the hangar for avionics or navigational equipment testing & calibration, troubleshooting, and repair. Safety is also enhanced as all aircraft service can be performed in a dry and clean indoor environment rather than outside where weather can become a factor. No more satellite acquisition delays for military planes leaving the hangar in a hurry.
Public safety vehicles including fire engines, emergency medical vehicles, and police cars are often equipped with equipment relying on a live GNSS signal. While in the parking garage or fire station, the satellite signal is usually lost. By installing GNSS repeater systems in the garage or fire station, you can ensure that all vehicles always receive a live signal and no delay is experienced in order to acquire the signal when leaving the station. Police officers and other Public Safety personnel using portable radios with GPS positioning will benefit from no acquisition time when leaving buildings with indoor GNSS signal coverage.
Service shops and maintenance depots can avoid having to move heavy equipment or vehicles outside for testing, calibrating, or maintaining the vehicle’s navigation devices. By installing a GNSS repeater system, mechanics can perform all their work inside the shop, avoiding costly towing back and forth. This also reduces heating & air conditioning costs as bay doors can be kept closed.
For retailers making GNSS enabled devices, having a reliable indoor satellite signal is beneficial when demonstrating features. For example, if there is no signal available, the demonstration of the product’s latest features based on GNSS in a new car becomes very challenging if not impossible. A GNSS repeater providing inside coverage will allow customers to compare different devices using “live” satellite signals as if outdoors.
Assembly Lines & Manufacturing
Manufacturing plants and assembly lines that produce equipment with embedded GNSS receivers can test, calibrate, and troubleshoot the GNSS device directly at the production line by installing GNSS repeaters inside the plant to save time and money. No need to bring equipment outside for test and calibration.
Testing & Laboratories
When you have a need to test any equipment relying on GNSS timing or location indoors, the lack of reliable satellite signal typically becomes an obstacle. By installing a GNSS repeater solution, you can rest easy knowing your personnel will have an excellent satellite signal in the lab or testing facility resulting in improved workflow and ROI.
