Models: RT-GPS or Turbo GPS
The RT-GPS transmitter is the same size, shape and weight of our RT transmitters, but inside we found a way to incorporate a tiny GPS receiver. The RT-GPS learns where it is and then sends this data via radio frequency to a transceiver we call the Pocketlink. It is the PocketLink that in turn forwards this situational data it is receiving to our App on your iPhone or iPad via Bluetooth. At the same time, the RT-GPS is sending a beeping signal in the UHF band that can be received by the Field Marshall for regular direction-finding.
The Turbo GPS communicates like the RT-GPS however when the transmitter stops hearing from the PocketLink it automatically kicks on the Turbo after 30 seconds of no contact. This allows 2-3 times the range with very little impact to battery life making it capable of sending the GPS signal great distances using situational awareness and intelligent response. When the transmitters hears from the PocketLink again it will automatically turn off the Turbo Mode.
For more difficult terrain, urban like areas, high wind conditions and areas that are challenging for recovery we recommend using the Turbo GPS model.
We recommend the tail option for optimal GPS positioning for your Parrot. Our Tail Mount option will come with two tail feather pieces and an installation tool. To learn more about how to install a tail feather piece you can follow the link. Tail Feather Piece Installation Kit
For Correct Sizing please include in notes the type of bird you are flying.
GPS BATTERY LIFE
The user configurable modes available within AeroVision allow the RT 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 with battery installed
- Battery used: rechargeable Lithium Battery (user swappable)
- Battery Life: 2-3 days with configurable modes to allow up to 7 days
- Antenna: 7 inch end-fed dipole diplexed with GPS
- RT-GPS Range: 1 to 30 miles*
- Turbo GPS Range: 2 to 100 miles*
*Measurements of distance are quoted using an Omni antenna. Conditions are variable depending on terrain and obstacles.
POCKETLINK BATTERY LIFE
The rechargeable lithium battery in the PocketLink lasts for 30+ hours, and is charged via a micro USB port. 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 leave if needed.
- 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 Bluetooth LE to iOS device
- AeroVision Mapping App
ADD AN OMNI TO YOUR SYSTEM
The PocketLink uses an SMA connector for quick attachment to Marshall’s UHF Omni antennas. In addition, the GPS system comes with a special 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.
DEVICES TO USE WITH YOUR SYSTEM
AeroVision Mapping App (downloadable from iTunes) requires:
- iPad Mini: Gen 2 or newer (cellular enabled)*
- iPad Air, iPad Air 2 (cellular enabled)*
- iPad Mini 4 (cellular enabled)* Recommended
- iPhone: 6 and newer
- iPhone 7 Plus or newer Recommended
* Note: Apple products are not sold by Marshall Radio. Also important: a cellular enabled iPad is required in order for it to have the needed GPS functions. However, you do not need to enable the cellular data plan to use AeroVision.
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:
- The size is less than half. This means it can be used as a leg or tail mount where other designs are far too large.
- The method is a direct connection, not dependent on nearby mobile towers, so it can be used anywhere without fear of “dead zones.” There is no SIM card to buy, therefore no waterproofing issues or further costs from text requests, etc. required to operate it. Simple. Reliable.
- Instead of periodic updates, delayed or irregular response to text inquiries this is real-time data streaming. You see where you bird is now, not just where it was.
- Our own innovative custom mapping application developed in-house makes it a joy to watch the flight, not a distraction. And you can also Replay or Share your flights (the same tracks and stats) with friends.
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) once every ten minutes in Morse Code (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 433-434) not only for tracking but communication and emergencies.
