Battery level is low. Charge the receiver.
●
Avoid using the receiver under an automobile windshield that contains metallic
wires or has been coated with a film, or in a house, tunnel, or underground parking
lot, or on a patio-like land, or near high-voltage cables, or in any other environment
where strong shield or interference presents. If you are using the receiver in any of
above environments, move it to a place with an open view to the sky.
●
If you will bring the receiver with you and use it, you should place it at an open
space and wait until it acquires the position and receives all ephemeris. This can
improve its performance.
●
For positioning purpose, place the receiver at an open space wherever possible.
The symptom can be improved if ideal satellite signals are received. A small drift
(an error within 10m) will not affect the position match between the photo and
the GPS coordinates.
