This kit fits the Fixposition VRTK, an RTK GNSS and vision positioning sensor, to the Deep Robotics X30 quadruped. It gives the robot centimeter-level outdoor positioning by fusing two RTK GNSS receivers with a global-shutter camera and an inertial measurement unit, rather than relying on satellite signals alone. It is an accessory; the X30 itself is not included.

It is meant for outdoor routes where the robot has to be in the same place every time: substations, plant yards, pipelines and perimeters patrolled on a schedule. With an RTK fixed solution, horizontal and vertical accuracy is 1.0 cm + 1 ppm (R50), and the two antennas give a heading accuracy of 0.4° on a 1 m baseline. Position, heading and velocity are output at up to 100 Hz in NMEA, ROS or Fixposition's own messages, with RTCM 3 correction input and a cold start under 25 seconds.

The camera and IMU keep the estimate going when satellite reception drops, for example beside tall structures. The drift figure given for a GNSS outage, 0.75% of distance traveled, applies to car mode with a wheel-odometer input; a legged robot provides no wheel odometer, so treat that figure as a reference rather than a promise for the X30.

Among the X30 payloads this is the positioning sensor. Its camera is part of the positioning engine; inspection imagery comes from a separate camera payload, and this kit works alongside one rather than replacing it. The sensor measures 114 × 129 × 30 mm, weighs 420 g, takes a 5-36 VDC supply from the robot and operates from -30 °C to +85 °C. Its typical power draw and the way its position output feeds your navigation software are confirmed with the quotation.

Key Capabilities

• RTK accuracy of 1 cm + 1 ppm: With an RTK fixed solution, horizontal and vertical positioning accuracy is 1.0 cm + 1 ppm (R50).
• Heading from two antennas: Dual GNSS-RTK receivers give a heading accuracy of 0.4° on a 1 m antenna baseline.
• Camera and IMU fusion: A global-shutter camera with a 120° diagonal view and an IMU feed the sensor-fusion engine alongside the GNSS receivers.
• Four satellite systems: It tracks GPS/QZSS, Galileo, BeiDou and GLONASS, each on two signal bands.
• Robot-ready outputs: Position is output at up to 100 Hz in NMEA, ROS or Fixposition messages, with RTCM 3 correction input.
• Wide operating range: The sensor works from -30 °C to +85 °C and takes its power from the X30.
