A software GNSS receiver is a Global Navigation Satellite System (GNSS) receiver that has been designed and implemented using software-defined radio.. A GNSS receiver, in general, is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position, velocity and time (of the receiver).
HP Universal Print Driver (UPD) is an intelligent print driver that supports a broad range of HP print devices, such as LaserJet and various MFPs. Developed by Hewlett-Packard , HP UPD combines a general purpose driver ( XPSDrv , UniDrv , or PSCRIPT ), print control, and HP proprietary extensions.
GNSS systems that provide enhanced accuracy and integrity monitoring usable for civil navigation are classified as follows: [5] GNSS-1 is the first generation system and is the combination of existing satellite navigation systems (GPS and GLONASS), with Satellite Based Augmentation Systems (SBAS) or Ground Based Augmentation Systems (GBAS).

A GPS receiver in civilian automobile use. Air navigation systems usually have a moving map display and are often connected to the autopilot for en-route navigation. Cockpit-mounted GNSS receivers and glass cockpits are appearing in general aviation aircraft of all sizes, using technologies such as SBAS or DGPS to increase accuracy.
Next is the handover word (HOW) giving the GPS time (as the time for when the first bit of the next subframe will be transmitted) and identifies the specific subframe within a complete frame. [11] [12] The remaining eight words of the subframe contain the actual data specific to that subframe. Each word includes 6 bits of parity generated using ...
The orbital period is one-half of a sidereal day, i.e., 11 hours and 58 minutes, so that the satellites pass over the same locations [92] or almost the same locations [93] every day. The orbits are arranged so that at least six satellites are always within line of sight from everywhere on the Earth's surface (see animation at right). [ 94 ]
The spine of federal data has always been the decennial census, the latest edition of which is being conducted this year. The kind of cross-section the census provides to officials at every level is impossible to beat, said Joe Salvo, the director of the population division in New York City’s Department of City Planning: “We may complain about the census, its warts and so on.
Assisted GNSS (A-GNSS) is a GNSS augmentation system that often significantly improves the startup performance—i.e., time-to-first-fix (TTFF)—of a global navigation satellite system (GNSS). A-GNSS works by providing the necessary data to the device via a radio network instead of the slow satellite link, essentially "warming up" the receiver ...
