Wednesday 2 October 2019:
Spectra Geospatial has released a notification that these receivers:
SP80, PM500, PM800, PF500, PF800, PM120, MM120
are unable to report positions because of an errant GLONASS ephemeris issue.
A firmware fix for the SP80 is available now. You can download it with this link: [ Version 3.45 ]
A fix for the remaining legacy devices is planned and should be available soon.
If you have an affected receiver you probably noticed problems beginning last Friday. There is a chance that the SP60 and SP20 are also affected as they share a common engine with the SP80, however the factory has not confirmed this.
Please note that this is not an official notice from the factory, this is a courtesy 'heads up',
