What people say about Marshall GPS!

I can make better decisions flying my birds. Even if I can’t see my bird I can glance at my phone and know where to look. How high the bird is, whether he’s sitting or if he’s flying. It gives all this crucial information that just makes life easier.

When I first was introduced to Aerovision it was back in February (2015) and what I thought about it was this is going to be a game changer because I go out and fly for abatement during the summer for blueberries and wine grapes… when I got out in the field I was able to see how far my bird was, how much area the bird was covering and also be able to show it to customers… it was surprising to see how much coverage the bird had done. …This has made my job so much easier.

You know why we love Marshall telemetry? Because this was the last photo taken of this anatum Peregrine before she decided to take a ride among the thermals. She flew about 100 miles north, decided to stay out two nights in a row and then eventually was recovered not too far from her flying field. Thankfully she had not just GPS on her but also a Marshall UHF RT transmitter, helping recover her days later. We are VERY happy she is home!

Marshall GPS · Turbo RF + GPS Telemetry

Range in the real world

Every GPS transmitter sends two signals: a live GPS track to the PocketLink, and a traditional UHF RF beep to your Field Marshall receiver. How far each reaches comes down to terrain — and your bird's altitude.

You + Field MarshallYou + PocketLinkBird

Open terrain high

With nothing between you and the bird, UHF travels essentially line-of-sight. This is where the quoted maximums are achieved — up to 200 miles of beeping RF and 100 miles of Turbo GPS data.

Open terrain low

As the bird drops toward the ground, both links shorten: the GPS data path weakens first as the horizon closes in, while the RF beep keeps giving you a bearing.

Forested / cover

Foliage and wet canopy absorb UHF energy, so expect ranges toward the lower end of the window. The traditional beep stays readable long after the data link drops — that's why both are on board.

Hilly / ridge

UHF is line-of-sight: a ridge between you and the bird can block the signal entirely. Move to high ground, or wait — the moment your bird climbs above the terrain, the beep returns first.

FAQs

What is the Marshall Turbo GPS System?

It is a tracking and recovery system designed for falconry. It uses a small GPS transmitter on the bird, a Pocketlink receiver, and the AeroVision app on your smartphone or tablet to show you the bird's exact location, flight path, and live statistics like speed and altitude.

Нужна ли системе сотовая связь для работы?

Нет. Система использует радиочастотный (RF) сигнал "Direct Connect" между передатчиком и приёмником PocketLink. Поскольку она не зависит от вышек сотовой связи, её можно использовать в любой точке мира, не беспокоясь о мёртвых зонах. Карты также можно скачать для работы без сети.

Нужны ли ежемесячная плата или SIM-карты?

Нет. Поскольку система связывается прямым RF-соединением, а не через сотовую сеть, нет SIM-карт, которые нужно обслуживать, и нет ежемесячной платы за сотовые данные для стандартных функций отслеживания.

Как долго работает аккумулятор передатчика?

У передатчика Turbo GPS сменные аккумуляторы. При настройках по умолчанию он работает 2-3 дня, но режимы в приложении можно настроить так, чтобы продлить работу до 7 дней.

Как долго работает аккумулятор приёмника PocketLink?

У PocketLink внутренний литиевый аккумулятор, который даёт 30+ часов работы между зарядками.

Какова типичная дальность отслеживания?

Дальность зависит от рельефа, высоты и препятствий. В среднем дальность отслеживания данных GPS составляет от 2 до 100 миль. Если птица на земле или вне дальности GPS, её традиционный телеметрический RF-сигнал «бип» можно отслеживать на расстоянии от 5 до 200 миль (с дополнительным приёмником радиопеленгации UHF).

Можно ли отслеживать несколько птиц одновременно?

Да. Один приёмник PocketLink может одновременно отслеживать до 5 передатчиков Turbo GPS, что удобно тем, кто летает с несколькими птицами.

Как закрепить передатчик на птице?

У передатчика конструкция, которую настраивает пользователь. Способ крепления легко сменить в поле и закрепить его на хвосте, спине, ноге или шее птицы.

Какие смарт-устройства совместимы с приложением AeroVision?

Пользователям Apple нужен iPhone 11 или новее либо iPad с сотовой связью под iOS 17 или новее. Для Android нужны модели более высокого класса, такие как Samsung S21/A52 или Google Pixel 6 под Android OS 11–14. (Примечание: планшеты должны быть "с сотовой связью", чтобы иметь необходимую внутреннюю аппаратуру GPS, даже если активный тариф данных не нужен).

Does the system come with a warranty?

Yes. Marshall Radio Telemetry provides a 3-year warranty on mechanical and moving parts, and a 3-year warranty on all electronics from the date of purchase.
