example 1

[0070] figure 1 Illustrated is a GNSS receiving device 100 such as a plug-in GPS receiving card for coupling with a host system such as a laptop computer, PDA, car computer, cell phone, etc., in accordance with an embodiment of the present invention. The receiving device 100 is configured to receive a host time signal 105 from a host system through a data interface port 110 . The data interface port 110 may also pass other signals related to the operation of the GNSS receiving device 100 such as location information and pass power and ground lines from the host system. During navigation operations, a host time signal 105 from the host system is provided to a navigation interface module 120 for receiving the host time signal. The navigation interface module 120 may also perform tasks such as requesting the host time signal 105 from the host system, providing the navigation time signal 125 to the satellite signal receiving module 130, deriving the navigation time signal based a...

[0076] figure 2 Illustrated is a GNSS-applied system including a GNSS receiving card such as a plug-in GPS receiving card coupled to a host system 250 such as a laptop computer, PDA, car computer, cell phone, etc., according to an embodiment of the present invention. device 100. Receiving device 100 is configured to receive host time signal 105 from host system 250 via data interface port 110, which receives the signal from host system 250 via data link 212, which connects data interface port 110 to host system 250. The corresponding data interface port 214 is connected. The data interface port 110 may also pass other signals related to the operation of the GNSS receiving device 100 , such as location information, and pass power and ground lines from the host system 250 . Other operations of the GNSS receiving device 100 are as described in Example 1.

example 3

[0079] image 3A method for operating a GNSS receiving device according to an embodiment of the invention is illustrated. In an initial step 310, a GNSS receiving device acquires a host time signal from a host system. The host time signal may be obtained by sending a request to the host system, or by periodically or continuously reading a signal transmitted by the host system indicative of the host time signal. In a subsequent step 320, the GNSS receiving device provides a navigation time signal based at least on the host time signal. For example, the navigation time signal may be essentially a replica of the host time signal when the host time signal is considered accurate, or the navigation time signal may be configured to reduce timekeeping imprecision based on information about the host real-time clock accuracy, drift, etc. A corrected version of the host time signal in degrees. In a subsequent step 330, the GNSS receiving device uses the time-of-navigation signal to co...

Abstract

The present invention provides a global navigation satellite system (GNSS) receiver apparatus, such as a GPS receiver, operable with a host computer system equipped with a real time clock configured to provide a time signal to the GNSS receiver apparatus. The time signal is used to facilitate acquisition of navigation and global timing information through observation of satellite signals. The global timing information is used to adjust the time signal and / or the real time clock to improve subsequent acquisitions of navigation and global timing information.

Description

technical field [0001] The present invention relates generally to Global Navigation Satellite System (GNSS) receivers, such as Global Positioning System (GPS) receivers, and in particular to GNSS receivers that can be coupled to a host system to provide mutual functional support. Background technique [0002] Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), are widely used to obtain precise location information based on observations of satellite signals. This location information can be used directly for navigation or provided to other devices such as computers or communication terminals to provide enhanced functionality. [0003] A particular challenge immediately following activation of a GPS receiver is obtaining the first fix in a timely manner. This challenge stems from the fact that, given a relatively unknown location, a GPS receiver requires highly accurate time information in order to locate and resolve satellite signals in t...
