gps receiver

a device that is capable of receiving information from GPS satellites and then to calculate the device’s geographical position. Using suitable software, the device may display the position on a map, and it may offer directions. GPS receivers are the most important hardware in a GPS surveying operation. Their characteristics and capabilities influence the techniques available to the user throughout the work. There are many different GPS receivers on the market. Some of them are appropriate for surveying,

GPS signal acquisition and tracking-An Approach towards development of Software-based GPS Receiver
free download

Abstract Software-based GPS (SGR) Receiver helps us processing the GPS signal at the lowest level of GPS raw signal data from the antenna. A software-based GPS receiver consists of a front-end device that converts the radio frequency signal from the antenna to an

Detection and mitigation of spoofing attacks on a vector-based tracking GPS receiver
free download

ABSTRACT Position solutions provided by GNSS receivers can be completely misled by spoofing attacks. Consequently detection and mitigation of spoofing signals have become one of the important topics within the GNSS community. Some recently published work has
