38 SPSx51 Modular GPS Receivers User Guide
•
On a vehicle or marine vessel, place the GPS antenna in a location as free from
shock and vibration as possible. For the modular GPS receivers, a single
magnetic mount is normally sufficient to hold the antenna in a suitable
location, whereas for the larger smart antenna, a triple magnetic mount is
normally recommended. Good alternatives include a 5/8" thread bolt in a
suitable location on the roof bars, or a door-mounted pole bracket.
•
To mount the modular GPS receiver on a pole, use two pole mounting brackets
and a second tripod clip (P/N 571 204 300). See

To mount the modular GPS receiver on a marine vessel, use the receiver bracket
(P/N 56830-00). For marine moving base and heading applications, use the
receiver bracket to mount two receivers together.
•
Make sure that the rover receiver does not lose power. An SPSx51 is typically
powered by its internal battery. You cannot change the battery, but the charge
typically lasts for longer than a working day. If you do not use the rover receiver
very often, ensure that it is charged at least every three months. For vehicle
operation or marine vessel operation, Trimble recommends that you use an
external power source so that the internal battery can be saved for times when
the receiver is being used off the vehicle or vessel.
