This guide will step you through retuning the StarFire ™ receiver to track changed satellite assignments for the
StarFire Network via NavCom’s StarUtil program.
Problem -

FCC National Broadband Plan asks for more mobile broadband

The FCC is looking to repurpose underutilized L-band satellite spectrum both above and below the GNSS
L1 band
 Moving StarFire™ to a higher L-band frequency to make designing robust filtering less challenging
Resolution – Update the receiver to the current release, as defined in the table above. Current products updated
with the new firmware (version v3.5.x.x) will include an updated StarFire tracking table and an over-the-air
StarFire almanac feature which allows for automatic updating of the tracking table should any statellites or
almanac feature for frequency changes which might occur in the future. This feature, the added capability of
GLONASS in StarFire, the accuracy improvements to <5cm
and futher planned improvements (don’t ask, we
can’t tell) are all good reasons to consider upgrading from the discontinued products to the current products.
The new software table was increased to handle up to 20 StarFire satellites.
Software for discontinued products does not contain an updated StarFire tracking table.
Follow the directions below to manually tune a discontinued receiver to the new frequency.
There are two phases of StarFire frequency changes. Net 2 StarFire frequencies were changed on November
1, 2014. Net 1 StarFire frequency changes will take effect June 12, 2015.
Graphical representation of the new global footprint is provided at the end of this document.
