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.

システムは動作に携帯電話サービスが必要ですか？

いいえ。システムは送信機とPocketLink受信機の間で「Direct Connect」の無線周波数（RF）信号を使います。携帯基地局に依存しないため、圏外を気にせず世界中で使えます。接続なしで使える地図をダウンロードすることもできます。

月額料金やSIMカードは必要ですか？

いいえ。システムは携帯電話網ではなく直接のRF接続で通信するため、維持するSIMカードはなく、標準の追跡機能に月額の携帯データ料金も不要です。

送信機のバッテリーはどのくらい持ちますか？

Turbo GPS送信機は交換可能な充電式バッテリーを備えています。初期設定では2-3日持ちますが、アプリケーションでモードを設定すると電池寿命を最大7日まで延ばせます。

PocketLink受信機のバッテリーはどのくらい持ちますか？

PocketLinkには内蔵の充電式リチウムバッテリーがあり、充電から充電まで30+時間動きます。

典型的な追跡到達距離はどのくらいですか？

到達距離は地形、高度、障害物によって変わります。平均すると、GPSデータの追跡到達距離は2から100マイルです。鳥が地上にいる場合やGPSの到達距離外では、従来のRFテレメトリーのビープ信号を5から200マイル追跡できます（オプションのUHF方向探知受信機を使用）。

複数の鳥を同時に追跡できますか？

はい。PocketLink受信機1台でTurbo GPS送信機を同時に最大5台まで追跡でき、複数羽を飛ばす方に最適です。

送信機を鳥にどう装着しますか？

送信機はユーザーが構成できる設計です。現場で装着方法を簡単に入れ替え、鳥の尾、背中、脚、首に取り付けられます。

AeroVisionアプリケーションに対応する機器は何ですか？

Appleの場合、iPhone 11以降、またはiOS 17以降を搭載したセルラー対応のiPadが必要です。Androidの場合、Android OS 11–14を搭載したSamsung S21/A52やGoogle Pixel 6のような上位モデルが必要です。（注：タブレットは、有効なデータプランがなくても、必要な内蔵GPSハードウェアを持つために「セルラー対応」である必要があります）。

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.
