What to do if Hemisphere GPS S320 Receiver fails to power on?
- P
  Paul HaydenAug 6, 2025
  If your Hemisphere GPS Receiver isn't powering on, several factors could be at play. First, examine the external power source, ensuring the external battery is adequately charged and the power cable's fuse is intact, if applicable. Next, verify the charge levels of the internal batteries. Inspect all power cables and pins for secure connections. Try using alternative, known-good batteries or cables to rule out faulty components. Ensure the batteries are installed correctly. Finally, make sure you press and hold the power button for at least one full second to initiate the power-on sequence.

What to do if my Hemisphere GPS S320 Receiver is not logging data?

  If your Hemisphere GPS Receiver isn't logging data, begin by checking the receiver's power status. Then, ensure the receiver is locked onto a valid DGPS signal and at least four GPS satellites. Check the integrity and connectivity of both the power and data cable connections. Verify that the baud rate settings of your devices match. If you're connecting via Bluetooth, confirm that the Bluetooth module is powered on and the device is properly paired before opening the port.

Why is my Hemisphere GPS S320 not showing a GNSS position?
- M
  Mark RussellAug 17, 2025
  If your Hemisphere GPS Receiver isn't showing a GNSS position, start by checking the antenna's view of the sky, particularly towards SBAS satellites, which are typically south in the northern hemisphere. Next, verify the bit error rate (BER) and lock status of SBAS satellites, using the receiving device or SLXMon to monitor the BER value. Ensure that the proper application (SBASRTKB) is running on the Eclipse. Set the satellite selection to automatic mode using the command $JFREQ,AUTO and the differential mode to $JDIFF,WAAS. Finally, confirm that there is SBAS coverage available in your current location.

How to fix random binary data from Eclipse OEM board on Hemisphere GPS S320?
- S
  smithkevinAug 25, 2025
  To resolve random binary data issues from the Eclipse OEM board on your Hemisphere GPS Receiver, first verify that RCTM or Bin messages are not being accidentally output by sending a $JSHOW command. Next, ensure that the baud rate settings are correctly matched. If the problem persists, the volume of data requested for output might exceed the current baud rate's capacity; consider using a higher baud rate for communications.

What to do if there is no DGPS position in external RTCM mode on Hemisphere GPS S320 Receiver?
- J
  Jennifer SwansonAug 30, 2025
  If you're not getting a DGPS position in external RTCM mode on your Hemisphere GPS Receiver, first verify that the baud rate of the RTCM input port matches the baud rate of the external source. Also, verify the pinout between the RTCM source and the RTCM input port: the ground pin and pinout must be connected, and the transmit from the source must connect to the receiver of the RTCM input port.
