FreshPatents.com Method and apparatus for mitigating the effects of cw interference via post correlation processing in a gps receiver
A positioning system receiver that mitigates the effect of continuous wave (CW) carrier interference with post correlation processing in a satellite positioning receiver, while not distorting the signal waveform or degrading receiver sensitivity and performing in low signal and dynamic interference environments....
FreshPatents.com Method and apparatus for mitigating the effects of narrowband interfering signals in a gps receiver
A positioning system receiver that mitigates narrowband interference by dynamically choosing the mitigation technique that yields the best interference mitigation capability with the least signal degradation to maximize receiver performance parameters such as receiver sensitivity, multipath resolution, and low power....
FreshPatents.com Location method and system and locatable portable device
Location method for locating a portable device (1) from a server (2) configured to communicate with said portable device (1) through a wireless communications network (3), in which said portable device (1) comprises a transmission/receiving module (12), an A-GPS positioning module (11) and a microprocessor (15) configured to manage said...
FreshPatents.com Portable communication terminal with gps function
This invention enables the MCT to automatically transmit the information on the position information and other information of the MCT at a predetermined time interval while the power of the MCT is on, and automatically transmit the information on the position information and other information of the MCT at the...
FreshPatents.com Integrity of differential gps corrections in navigation devices using military type gps receivers
A method and apparatus for calculating corrections to a navigation solution based on differential GPS data includes receiving GPS ephemeris from at least three GPS satellites. A PVT solution is resolved from the GPS ephemeris. The PVT solution includes a Circular Error Probable (CEP). Differential GPS data for calculating the...
FreshPatents.com Method and apparatus for mitigating the effects of cross correlation in a gps receiver
A positioning system receiver that mitigates cross correlation of received signals from positioning system satellite vehicles by generating the strong satellite vehicle signal and subtracting it from the received signal before correlation while eliminating the need for cross correlation signature without changing the C/A code....
FreshPatents.com Method and apparatus for real time clock (rtc) brownout detection
A method and apparatus for real time clock brownout detection. A low power real time clock (RTC) operates continuously to keep time in a global positioning system (GPS) receiver while some receiver components are powered down. In various embodiments, a brownout detector circuit detects a loss of RTC clock cycles....
IEEE Pipeline Forwarding of Packets Based on a Low-Accuracy Network-Distributed Common Time Reference
Pipeline forwarding is a technology with the capability of providing both guaranteed quality of service (QoS) and scalability, two fundamental properties for the future Internet. Implementing pipeline forwarding requires network nodes to operate with a common time reference that, in existing literature, is considered to have relatively good accuracy and usually be derived from an external source, such as the GPS or Galileo. This is a major requirement possibly hindering the widespread deployment of this te...
ZDNet Nokia E63
Although it's missing some features (chiefly HSDPA and GPS), Nokia's E63 is a well-thought-out, ergonomic and affordable smartphone.
ZDNet BlackBerry Curve 8520
RIM's latest BlackBerry seeks to attract more than just its core business user base. But will the lack of 3G and GPS count against it?
