This paper conducts some essential theoretical research on navigation terminal test.Technical details are studied including model set up,project design and simulation verification.Moreover,based on th
Multipath interference is the main source of error in the urban environment.In order to effectively suppress multipath interference and improve the continue tracking performance.
The spectrum of four global satellite navigation systems allocated on the L1 band are severely overlapped,which makes signal interfere inevitably.Effective carrier power-to-noise density ratio ((C/N0)
An important observation of GNSS-R is Delay-Doppler mapping (DDM).According to the requirement of GNSS-R signal real-time processing,a fast processing algorithm of GNSS-R signal based on double block
Mobile phone equipped with WiFi,Bluetooth,MEMS-IMU,and other sensors is a perfect platform to provide location based service for personal users.For positioning using wireless signals,the fingerprints
GNSS-R is a new branch of GNSS which has been developed since the 1990s.It can be applied to remote sensing exploration of marine environment and remote sensing of terrestrial environment.
With the development of Global Navigation Satellite System (GNSS),Multi-GNSS combined real-time precision positioning has become the current trend of GNSS application.Though every navigation system ca
with the continuous promotion of Beidou satellite navigation applications,the pace of city market accelerate,and how to improve the navigation terminal performance is a hot issue under city environmen
