A "GNSS compass" uses a pair of antennas separated by about 50 cm to detect the phase difference in the carrier signal from a particular GNSS satellite. [8] Given the positions of the satellite, the position of the antenna, and the phase difference, the orientation of the two antennas can be computed.
Image sensor format — the sizes and shapes of common image sensors Exmor - the exact sizes of Sony Exmor sensors, often mentioning the camera(s) using them. Sony sells some of theses sensors to other camera manufacturers.
Canon printers are supplied with Canon Advanced Printing Technology (CAPT), a printer driver software stack developed by Canon. The company claims that its use of data compression reduces their printer's memory requirement, good quality compared to conventional laser printers, and also claim that it increases the data transfer rate when ...
The method is applicable for any GNSS/INS system. Overview. GPS/INS method ... In general, GPS/INS sensor fusion is a nonlinear filtering problem, ...
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 ...
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).
The US Nationwide Differential GPS System (NDGPS) was an augmentation system for users on U.S. land and waterways. It was replaced by [dubious – discuss] NASA's Global Differential GPS (GDGPS) system, which supports a wide range of GNSS networks beyond GPS. The same GDGPS system underlies WAAS and A-GNSS implementation in the US. [11]
This formula for Q arises from applying best linear unbiased estimation to a linearized version of the sensor measurement residual equations about the current solution _ = (()), except in the case of B.L.U.E. is a noise covariance matrix rather than the noise correlation matrix used in DOP, and the reason DOP makes this substitution is to ...
