FreeFlight System’s RANGR 978MHz ADS-B Datalink provides a low cost, light-weight solution for becoming ADS-B compliant and adding datalink traffic and weather in the aircraft.

Automatic Dependent Surveillance-Broadcast (ADS-B) technology is the new advanced airspace management system currently being implemented worldwide. In addition to ATC situational awareness, expanded radar coverage and search and rescue capabilities, the 978 MHz system (available only in the United States) offers traffic information and free datalink weather. The FreeFlight Systems RANGR family provides a low-cost, light-weight ADS-B compliant solution for general aviation aircraft flying in the United States below 18,000 feet.

Full ADS-B Compliance

The final FAA rule dictates an ADS-B compliant system must have a high integrity position source and a radio that sends specific information from that position source to ATC. The easiest way to achieve this requirement is to pair a TSO-C145/C146 WAAS GPS with an ADS-B approved transmitter. In addition, 978MHz compliance requires a small control head for entering squawk codes.

The RANGR family allows customers the most flexibility by offering complete stand-alone solutions with certified GPS and 978MHz transmitter all-in-one or separate, modular solutions to interface with current systems in the aircraft. This will keep cost to the customer as low as possible while still achieving ADS-B compliance. Add the receive functionality and the customer receives additional benefit beyond the standard ATC coverage.


When coupled with an ADS-B receiver, the FAA will send a customized traffic picture relative to aircraft position. Because it is relative to aircraft position it is crucial to have a GPS installed with the proper integrity. As more aircraft are equipped with ADS-B, direct communication with other aircraft will also be available. All RANGR systems will offer dual antennas for improved traffic coverage.


The same datalink weather available today through monthly service providers is available through ADS-B at no charge. The weather can be displayed on any compatible MFD, EFB or IPAD display. This is only available on 978Mhz receivers and will eventually require a valid ADS-B transmission to receive the data.
