GPS RTK Base GPS Receiver User Guide 31

Setup Guidelines 4

• Do not set up the base station directly beneath or close to

overhead power lines or electrical generation facilities. The

electromagnetic fields associated with these utilities can

interfere with GPS receiver operation. Other sources of

electromagnetic interference include:

– Gasoline engines (spark plugs)

– Televisions and computer monitors

– Alternators and generators

– Electric motors

– Equipment with DC-to-AC converters

– Fluorescent lights

– Switching power supplies

• Place the GPS receiver in a protected and secure location.

• If you place the AgGPS RTK Base 450/900 receiver in a lock box or

other enclosure to protect the receiver from theft or from the

weather, shield the lock box from direct sunlight and provide

ventilation for the receiver through an inlet and extractor fan. A

receiver that has a broadcast radio generates significant heat. Do

not allow the temperature in the box to exceed 50 ºC (122 ºF).

• If working in a cold climate, you may need to provide heat to the

receiver. Do not operate the receiver below –40 ºC (–40 ºF).

• Trimble recommends that, wherever possible, you keep GPS

receiver equipment dry. The receivers are designed to withstand

wet weather, but keeping them dry prolongs their life and reduces

the effects of corrosion on ports and connectors. If the equipment

gets wet, use a clean dry cloth to dry the equipment and then

leave the equipment open to the air to dry. Do not lock wet

equipment in a transport case for prolonged periods. Avoid

exposing the GPS receiver to corrosive liquids and salt water

wherever possible.
