TobyRich has integrated OriginGPS’ Nano Hornet into a smartphone-controlled gaming drone line, to extend its range and enhance its directional capabilities. By leveraging the Nano Hornet, a tiny GPS module with an integrated antenna, TobyRich was able to design a smaller, sleeker form factor for its innovative drones while taking advantage of OriginGPS’ performance and low-power consumption features, according to... read more

Tallysman Launches Higher Gain Dual-Frequency Antenna

August 19, 2015By

Tallysman, a manufacturer of high-performance GNSS antennas, has launched a higher gain dual-frequency embedded antenna: the TW3870E. The TW3870E antenna has a typical gain of 35 dB which is required by some GNSS receivers, such as Trimble’s BD9xx family of receivers. The antenna is capable of receiving GPS L1/L2 and GLONASS G1/G2 signals. It employs Tallysman’s Accutenna technology, which can... read more

Chip Transition-Edge Based Signal Tracking for Ultra-Precise GNSS Monitoring Applications
This novel concept of monitoring chip asymmetry can extend the state of the art in the areas of GNSS signal-quality monitoring and authentication. Tracking GNSS signals using their underlying spreading sequence chip transition edges reveals positive versus negative chip asymmetries that are characteristic to each satellite. This asymmetry is due to various types of natural signal deformation that is known to occur within the satellite’s signal generation and transmission hardware. read more
