T4 GPS Tracking System
Tiny Telemetry Tracking Transmitter!

Straight from your rocket, rail to recovery! The T4 carries a uBlox M10 GNSS receiver tracking multiple constellations at once, and it downlinks your position live for the whole flight. Pair it with an RRC4 and the same link carries your full flight telemetry too.

Not Just GPS
More birds in view, faster fixes!

The uBlox SAM-M10Q receives GPS, GLONASS, Galileo and BeiDou concurrently, with SBAS and QZSS augmentation. That means a faster fix on the pad and quicker reacquisition on the way down. A SAW filter and LNA built into the module keep the receiver hearing faint satellite signals, even inches from a 1 watt transmitter.

• uBlox SAM-M10Q with four concurrent GNSS: GPS, GLONASS, Galileo and BeiDou
• SBAS (WAAS/EGNOS) and QZSS augmentation, enabled by default
• Embedded 15 × 15 mm patch antenna, so there’s nothing external to mount
• SAW filter and LNA ahead of the receiver
• Jamming and spoofing detection, reported to the host

Standalone or Paired
A tracker on its own, a telemetry link with the RRC4!

Give the T4 a battery and it’s a complete GPS locator. It downlinks your position the whole flight and gives you a live bearing to walk in on after landing. Add an RRC4 and the downlink also carries altitude, velocity, events and battery voltage alongside position, live for the whole flight.

Two Radios, One Board
Pick your range!

Both radios use the same footprint and mounting. The XR Pro simply gives you a great deal more link.

• Standard: XBee Pro S3B 250 mW (24 dBm). Up to 9 mi line-of-sight on dipoles, and up to 28 mi with high-gain antennas. Antenna is the integrated quarter-wave whip or u.FL. Powered by the RRC4 through a 4-wire cable.
• Long range: XBee Pro XR 1 W (30 dBm). About 20 mi line-of-sight on dipoles, and up to 65 mi with high-gain antennas. Antenna is u.FL only. Runs its own battery through a 3-wire cable.
• 902–928 MHz ISM band, frequency hopping

One Cable to the RRC4
One battery, one switch, one cable!

A single ZH 1.5 mm jumper links the T4 to your RRC4. With the 250 mW radio, the RRC4 supplies the T4’s 3V3, so there’s nothing else to wire, charge or arm. The 1 W XR Pro draws high current in hard bursts every time it keys up. It runs from its own battery and the link to the RRC4 is data only, so that current never reaches the rail your flight computer relies on.

Lands in Vector GS
Live on the pad, live through the flight!

• Live telemetry: altitude, velocity, and axial and lateral G, plotted as they arrive
• Flight state: boost, coast, apogee, drogue and main, called out as they happen
• Pyro and health: channel status, battery voltage, baro temperature and GPS fix quality
• Map and heading: position on the map and a bearing to walk in on after landing
• One app on Android and iOS, coming to Google Play and the App Store

Elevate your rocketry to new heights!

Range figures are line-of-sight, meaning a clear path between your rocket airframe and your receiver. Nearby objects can absorb, block or reflect signal energy and detune the antenna. Use the dipole figures for most sport flying, and the high-gain figures for extreme high-performance projects.
