How do I connect the Orbit GPS to my flight controller?

Connect the 4-pin CAN cable connector from the Orbit GPS to either the CAN1 or CAN2 port on your flight controller. The pinout is:

  • Red: VCC_5V
  • Red: CAN_H
  • Black: CAN_L
  • Black: GND

What firmware does Orbit GPS support?

Orbit GPS supports both Ardupilot and PX4 firmware systems. PX4 firmware version 1.12.3 and above supports automatic node ID allocation.

What voltage does the Orbit GPS require?

The system operates on 4.75V - 5.25V DC power supply.

Performance & Features

What is the position accuracy of Orbit GPS?

The horizontal position accuracy varies by mode:

  • PVT: 1.5m CEP
  • SBAS: 1.0m CEP
  • RTK: 0.01m + 1ppm CEP

What is the maximum update rate?

  • GPS + Multi-GNSS: Up to 10 Hz
  • GPS Only: Up to 25 Hz

Troubleshooting

Why is my GPS LED flashing blue?

A flashing blue LED indicates the system is disarmed and hasn’t acquired a GPS lock. Ensure you have a clear view of the sky and wait for GPS acquisition.

The LED is showing solid red, what should I do?

Solid red typically indicates a critical system error. Check:

  1. SD card connection and format
  2. Power supply stability
  3. System connections If the issue persists, try rebooting the system.

How can I improve GPS signal reception?

  1. Mount the antenna with a clear view of the sky
  2. Keep the antenna away from sources of electromagnetic interference
  3. Ensure proper antenna orientation

What should I do if the GPS won’t connect to my flight controller?

  1. Verify the CAN bus parameters are set correctly
  2. Check cable connections
  3. Ensure firmware compatibility
  4. Confirm power supply is within specified range (4.75V - 5.25V)

Maintenance & Care

Does the Orbit GPS require any regular maintenance?

Regular maintenance includes:

  1. Checking cable connections
  2. Ensuring antenna cleanliness
  3. Verifying mounting security
  4. Updating firmware when available
