The AT1 is a rechargeable, portable GPS tracker with a strong built-in magnet that fixes to any metal surface without tools or permanent installation. What sets the AT1 apart is its flexible battery management: choose between standard mode for frequent location updates or power-saving mode to dramatically extend battery life between charges. This makes the AT1 ideal for long-term asset tracking, personal use, or vehicles you can’t easily access to recharge regularly.

Setup & Placement

1

Charge the battery

Before first use, fully charge your AT1 using the included magnetic charging cable. Attach the magnetic charging connector to the charging port on the device and connect the other end to a USB power source. A full charge typically takes 2–4 hours depending on the battery level. The LED indicator will change to confirm a full charge.
2

Power on the device

Press and hold the power button for 3 seconds until the LED flashes. The AT1 will begin searching for GPS signal and connecting to the 4G network.
3

Choose your battery mode

Before placing the device, select the battery mode that suits your use case in the ShieldGPS app:
  • Standard mode — location updates every 10 seconds; ideal for active vehicle tracking or short-term use where frequent updates are needed.
  • Power-saving mode — less frequent location updates to significantly extend battery life; best for long-term asset tracking or situations where you won’t be able to recharge the device regularly.
You can switch between modes at any time from the device settings in the app.

Choose your placement location

Use the strong built-in magnet to attach the AT1 to any metal surface. Good hiding spots include the underside of a vehicle chassis, inside a wheel arch, behind a metal interior panel, or underneath metal equipment. Make sure the chosen spot has some exposure to the sky (even through thin metal or plastic) for a reliable GPS signal.
5

Attach the device

Press the AT1 firmly onto the metal surface. Give it a light tug to confirm the magnet has a solid hold. For rough terrain or high-vibration environments, reinforce the placement with a cable tie or adhesive pad.
6

Confirm tracking in the app

Open the ShieldGPS app and verify your AT1 is showing a live location on the map. Check the battery level indicator to monitor charge status at a glance.

​
Powering On & First Use

Press and hold the power button for 3 seconds to turn the AT1 on. On first use, take the device outside or to an area with a clear view of the sky, and allow up to 2 minutes for the device to:
  1. Acquire a GPS fix
  2. Connect to the 4G network
  3. Begin transmitting location data to the ShieldGPS platform
To power off the device, press and hold the power button for 5 seconds until the LED turns off.

​
Check tracking in the app

1

Open your tracker

Open the ShieldGPS app or web dashboard and sign in with the account you used during activation. Select your AT1 from the device list — activation adds it to your account automatically.
2

Confirm live tracking

Your AT1 will appear on the map. Tap the device icon to see its current location, battery percentage, and movement status.

​
Battery Modes Explained

Standard Mode

Location updates every 10 seconds. Use this mode when active, real-time tracking is your priority — for example, tracking a vehicle in motion or monitoring an asset you expect to move soon.

Power-Saving Mode

Less frequent location updates to extend battery life between charges. Use this mode for long-term asset tracking or when you can’t easily access the device to recharge it.

LED Indicator Meanings

Switch to power-saving mode whenever you don’t need real-time updates. This can extend battery life considerably, reducing how often you need to retrieve and recharge the device — particularly useful when the AT1 is hidden in a hard-to-reach location.
Do not use a third-party charging cable with the AT1. The magnetic charging connector is proprietary — using an incompatible cable may damage the charging port or fail to charge the device correctly.
