Marshall GPS System
The Marshall GPS System is hands down, the fastest and safest way to track and recover your Bird. No longer are you left guessing when your raptor is out of sight.
How does it work?
The Marshall GPS System consists of three main components. The Turbo GPS Transmitter, the PocketLink Data Receiver, and the AeroVision App on your Smart Phone or Tablet. The Turbo-GPS transmitter is the same size, shape and weight as our traditional telemetry transmitters, but inside we’ve found a way to incorporate a tiny GPS receiver. With a clear view of the sky, the Turbo-GPS acquires it’s position, then sends this data via radio frequency signal to a data receiver we call the Pocketlink. It is the PocketLink that in turn forwards this information over Bluetooth, to AeroVision running on your smart device. At the same time, the Turbo-GPS sends a traditional beeping signal that can be tracked by the Field Marshall UHF Direction Finding Receiver. The Turbo-GPS transmitter builds on the earlier RT GPS, by smartly increasing its tracking range anytime the transmitter is out of range of the PocketLink, while at the same time slowing down GPS updates. This enables 2-3X the tracking range of the original RT GPS, while minimal impact to battery life making it capable of sending the GPS data at great distances using situational awareness and intelligent response. When the transmitters comes back into range of the PocketLink again, it will automatically transition back to standard GPS update rate.
The PocketLink can be used in the with the included short antenna for ultimate portability, or connected to the optional High Gain Omni for extended range while tracking from the car. The PocketLink can simultaneously track up to 5 Turbo GPS
GPS BATTERY LIFE
The user configurable modes available within AeroVision allow the Turbo GPS to run for up to a week on the rechargeable battery. Mixed mode use can be configured for several hours of high update GPS plus many hours of lower update rate tracking. Default settings the battery life is 2-3 days.
- Weight: 9 grams incl. battery
- Battery: rechargeable Lithium Battery (user changeable w/spare)
- Battery Life: 2-3 days with configurable modes to allow up to 7 days
- Antenna: single 7 inch whip
- Turbo GPS Range: 2 to 100 miles*
*Measurements of distance are quoted using an Omni antenna; varies depending on terrain and obstacles.
POCKETLINK BATTERY LIFE
The PocketLink’s internal lithium battery provides 30+ hours of runtime, and is charged via micro USB. Since the battery has built in intelligence, there is no “memory” and you can also leave it plugged in to the vehicle at all times to stay “topped-off” and ready to Field use at anytime.
- Weight: <12 oz
- Battery used: 3.7V LiPo internal (rechargeable through Micro USB cable provided)
- Battery life: 30+ hours
- Antenna connection: SMA
- Range: up to fifty (50) feet via BTLE to Phone/Tablet
ADD AN OMNI TO YOUR SYSTEM
The PocketLink uses an SMA connector for quick attachment to Marshall’s High Gain UHF Omni antenna. Also available as an option for those hawking away from the car is an SMA-SMB adapter cable that allows the UHF Yagi on your Field Marshall UHF receiver to be used to boost range while on foot in the field.

RECOMMENDED ITEMS TO ADD TO YOUR SYSTEM
- Field Marshall UHF receiver
- UHF Turbo/RT/ or Micro (recommended as the secondary backup transmitter)
The Field Marshall Receiver allows you to track the beeping signal of your GPS transmitter or when you are in “Plan B Mode” the UHF receiver is needed to track your backup UHF regular telemetry transmitter.
The difference between our GPS system and other GPS devices for falconers
Four main ways, in combination:
- Smallest and most rugged design, providing the most reliable GPS experience possible.
- Swappable batteries – start each flight with a fully charged battery.
- User configurable mounting – easily swap from Tail to back, leg or neck mount.
- Direct RF connection – not dependent on nearby mobile towers, so it can be used anywhere in the world without fear of “dead zones.” No SIM card to maintain therefore no waterproofing issues or further costs from text requests, etc. required to operate it. Simple. Reliable.
- Real time GPS updates – not delayed or irregular response waiting for an SMS. You see where you bird is now, not just where it was.
- Live tracking of up to 5 transmitters, simultaniously.
- Best in class App w/ offline Maps, developed in house: makes it a joy to watch the flight, not a distraction. You can also Share your flights live with your firends or Replay in 3D .
These key features have not been available until now.
What are the regulations in the US and Canada for using the UHF bands?
The use of the 434 (or UHF) band in the USA & Canada requires the user to apply for a Ham Radio License (easily attainable by paying a small fee and passing a written test). Once done, the user is now a legal ‘station’ and is able to use the quiet UHF band and at much higher power levels. To legally use telemetry on this band, your transmitter must broadcast your station ID (Ham Radio Call Sign, a feature exclusive to Marshall transmitters). You simply enter your call sign or temporary station ID (phone number) into AeroVision.
If you do not have an Amateur Radio License, you might be surprised how easy it is to obtain one. Pass a simple test, for which you can study all the answers in advance, pay ten dollars and with and 80% passing grade, you have a ten-year license, new knowledge about Radio Telemetry and the authorization to use the non-commercial bands (such as 434MHz) not only for tracking but communication and emergencies.
