Glossary Almanac data A set of information that transmitted by each satellite on the orbits and state of every satellite in the GPS constellation. Each GPS satellite contains and transmits the almanac data set for the entire GPS satellite system network. Almanac data allows the GPS receiver to rapidly acquire satellites shortly after it is turned on. ACTIVE ANTENNA An antenna that amplifies the GPS signal before it sends it to the receiver.
Constellation Constellation refers to the specific set of of orbiting GPS satellites system, used in calculating positions or all the satellites visible to a GPS receiver at one time. The pattern created by the relative positioning of a GPS satellite network is designed to achieve a very high probability of global satellite coverage even in the event of satellite outages. dB Decibel. A notation of relative unit such as the satellite signal strength received.
GIS (Geographic Information System) a computer based system that is capable of collecting, managing and analyzing geographic spatial data. This capability includes storing and utilizing maps, displaying the results of data queries and conducting spatial analysis. Hot Start Start mode of the GPS receiver when current position, clock offset, approximate GPS time and current ephemeris data are all available. L1 frequency 1575.
much wider bandwidth than the signal information bandwidth. This provides the ability to receive all satellites unambiguously and to give some resistance to noise and multipath. TIME TO FIRST FIX (TTFF) The time it takes to find the satellites is called the Time to First Fix (TTFF). If you have not used your GPS unit for several months, the almanac data for the satellites may be out of date. The unit is capable of recollecting this information on its own, but the process can take several minutes.
