How to troubleshoot Simrad Marine GPS System receiver that fails to power?
If your Simrad Marine GPS System receiver fails to power on, there are several things you can check. First, verify that the NMEA 2000® backbone is powered. Next, check the voltage coming out of the connector at the end of the cable. Finally, ensure that the power source meets the minimum current requirements; it should be greater than 1.0 A.
Why Simrad Marine GPS System shows no heading or incorrect heading value?
If your Simrad Marine GPS System is not providing heading data or the heading value is incorrect, ensure that at least four satellites show a strong SNR value on both antennas. Also, make sure the arrow on the underside of the HS75 is directed to the bow, as the heading is determined from the primary to the secondary GNSS antenna.
What to do if no data from Simrad HS 75 HS75?
If your Simrad Marine GPS System HS75 is not transmitting data, first ensure that the NMEA 2000® backbone is powered. Then, check the integrity and connectivity of all cable connections.
How to fix Simrad Marine GPS System no GNSS lock?
If your Simrad Marine GPS System cannot get a GNSS lock, make sure that the HS75 has an unobstructed view of the sky.
Why Simrad Marine GPS System has no SBAS lock?
If your Simrad Marine GPS System cannot obtain an SBAS lock, first ensure the HS75 has a clear view of the sky. Also, SBAS lock is only possible if you are in an appropriate SBAS region. Currently, there is limited SBAS availability in the southern hemisphere.
