each of the satellites individually, by listening for each satellite's distinct spreadspectrum hopping sequence. This process can take a few minutes while the
receiver uses an iterative process to locate satellites, refine its position, and
determine which satellites to search for.
When the power to the GPS receiver is turned off, the receiver remembers the
last known position; this results in faster satellite acquisition the next time it is
turned on. However, if the antenna has been moved more than a few miles
acquisition time is slightly longer, since the receiver must first re-compute the
position.
The GPS receiver is built into the antenna housing, and communicates to the
board via a serial (RS-422) interface. Power (+12V) is supplied from the board.
The unit comes with a 100-foot cable. Extension cables are available, in 100-foot
lengths. The maximum total length is 500 feet. Since the connectors on the
extension cables are not weatherproof, only the first 100 feet can be outdoors.
The cable consists of several twisted pairs (not co-axial cable), and a foil shield.
Inspection
Unpacking the Unit
After unpacking the unit, inspect it carefully for any possible damage to
connectors or components. Should you discover any damage, report it to KSI
immediately. Full information for reaching KSI can be found on the back page of
this manual.
