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.

系统工作需要蜂窝网络吗？

不需要。系统在发射头与PocketLink数据接收器之间使用"Direct Connect"射频（RF）信号。它不依赖基站，因此可以在世界任何地方使用，不必担心信号盲区。您也可以下载地图供离线使用。

需要月费或SIM卡吗？

不需要。系统通过直接RF连接通信，而不是蜂窝网络，因此没有需要维护的SIM卡，使用标准追踪功能也不需要每月的蜂窝数据费。

发射头的电池能用多久？

Turbo GPS发射头采用可更换的可充电电池。默认设置下可用2-3天，但您可以在应用程序中配置模式，将电池续航延长至最多7天。

PocketLink数据接收器的电池能用多久？

PocketLink数据接收器具有内置可充电锂电池，两次充电之间可运行30+小时。

典型的追踪范围是多少？

范围取决于地形、高度和障碍物。平均而言，GPS数据追踪范围是2到100英里。如果鸟在地面上或超出GPS范围，可以在5到200英里内追踪其传统射频遥测蜂鸣信号（使用可选的UHF测向接收器）。

可以同时追踪多只鸟吗？

可以。一台PocketLink数据接收器可以同时追踪最多5个Turbo GPS发射头，非常适合同时放飞多只鸟的用户。

如何把发射头装到鸟身上？

发射头采用用户可配置的设计。您可以在野外轻松更换安装方式，把它固定在鸟的尾、背、脚或颈上。

哪些智能设备兼容AeroVision应用程序？

Apple用户需要iPhone 11或更新机型，或运行iOS 17或更高版本的蜂窝网络版iPad。Android需要较高端机型，例如运行Android OS 11–14的Samsung S21/A52或Google Pixel 6。（注：平板必须是"蜂窝网络版"，才具备所需的内置GPS硬件，即使您不需要有效的数据套餐）。

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.
