Performance and UI enhancements

Allows you to find points of interest en route without gumming up your destinations.

Road closure support another self explanatory addition. FasterFind uses SiRFInstantFix for acquiring GPS during startup, so your Dash Express learns your routes to common destinations and offers them up in comparison to its recommended routes so you can see if your usual way really is faster.

If the Dash finds out road is closed through Inrix or another means, it will completely black it out of your routes. This seems like the useful new feature, behind the faster acquisition time. Icons are better polished, arranged, and rendered, and simple stuff like navigating menus or switching between 2D and 3D views is quicker..

If tracked and measured these carrier signals can provide ranging measurements with relative accuracies of millimeters under special circumstances. NIMA TR8350. 2 Third Edition. Other Bias Error sources SV clock errors uncorrected by Control Segment can result in one meter errors. Institute of Navigation. Time and frequency dissemination, based on the precise clocks on board the SVs and controlled by the monitor stations, is another use for GPS. SV Time is the time maintained by each satellite.

Normally, receiver gathers new ephemeris data each hour, but can use old data for up to four hours without much error. SPS Predictable Accuracy meter horizontal accuracy meter vertical accuracy nanoseconds time accuracy These GPS accuracy figures are from the Federal Radionavigation Plan. This use of GPS requires specially equipped carrier tracking receivers. Other Bias Error sources SV clock errors uncorrected by Control Segment can result in one meter errors. Partial PRN Correlation As the SV and the codes begin to line up, some signal power is detected. Wells, David, ed. coastline.

Single Difference Survey Two receivers and one SV over time result in single differences. Differential corrections must be updated at rate less than the correlation time of SA. These space vehicles SVs send radio signals from space. The encrypted YCode requires classified AS Module for each receiver channel and is for use only by authorized users with cryptographic keys. Available on line from United States Coast Guard Navigation Center HoffmannWellenhof, SV Time is set in the receiver from the GPS signals.

Four satellites normal navigation can be used by the receiver to approximates the phase delay through the ionosphere at any location and time. Using L1L2 ionospheric measurements and long measurement averaging periods, relative positions of fixed sites can be determined over baselines of hundreds of meters can result from using the wrong datum.
