If you’re flying fire service missions you recognize the need for AFF (Automated Flight Following) technology to maintain safety and situational awareness. To be compliant and continue serving, an ATU (Additional Telemetry Unit) device is also required. Let’s face it; new technology seems disruptive—it can add work, and make it hard to keep up. However, it also offers unique opportunities for operators and the teams that support them. Guardian Mobility’s G4 family suite of products has you covered with hardware and software—from walking to the aircraft to the drive home—all backed by superior customer support. G4 AFF devices automate the collection of data for logbooks, maintenance data, and flight tickets so you can get back to flying.
With the industry’s highest level of precision, complete flight detail from power-on to power-off is recorded for more accurate billing and maintenance documentation. Our solution saves you time, reduces inaccuracies and supports operational efficiencies while also maintaining safety. Once equipped with AFF and ATU, aircraft location, bucket or tanks volume, drop information and velocity are tracked. The data is provided in near real-time to dispatchers, aviation managers, and other authorized users—offering critical insights to the team. Like the whole G4 product family, Guardian Mobility’s G4MX device provides global, real-time user tracking and two-way messaging in a single unit. ATU and FDMS compliant, and field-upgradable, the G4MX is flexible and scalable, offering a streamlined migration path. Start with basic tracking and communication, and easily upgrade to advanced capabilities with the same device—saving time and money, because a new one need not be purchased.
