what's the advanced planning about data cable for Trimble Surveying Instruments
- May 15, 2018 -

It is time well spent to estimate in advance the cable length from the GPS antenna to the receiver for any planned installation. Cable lengths that are too short or too long can each introduce problems. In some cases adding an inline amplifier and some extra cable may be a quick and economical solution. In other instances retrofitting for a GPS down/up converter may be necessary which will require installing a different cable type. Keep in mind that some extra cable coiled in a ceiling leftover from over estimating the cable length is not necessarily negative. Provided you know the length of the total cable, the cable delay can be accounted for and the timing accuracy maintained.
