Quartz Flexible Accelerometer

Quartz flexible accelerometer series is a high-precision inertial navigation class accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability.

Fiber-Optic GYROSCOPE

This product consists of two parts: optical angular velocity sensitive unit and signal detection, providing uniaxial angle increment information and internal temperature information

MEMS GYROSCOPE

applications are typically found within Industrial, for various platform stabilizations, pointing and navigation systems, attitude heading reference systems , inertial navigation systems, 3D mapping systems, range finders, trains,robotics and more.

KT-140FA anti-jamming GNSS receiver(2024)

KT-140FA integrated anti-jamming antenna satellite receiving unit can receive GPS-L1 at the same time1+BDS-B1perhaps BDS-B1+GLONASS-L1Satellite navigation signal can realize single system and joint positioning navigation; can realize GPS-L1+BDS-B1perhaps BDS-B1Anti-interference function of the signal of the + GLONASS. The anti-interference antenna integrates anti-interference RF chip, medium frequency filter, four-channel ADC, anti-interference digital processing chip, DAC, upconversion mixer, radio frequency converter, RF selection switch and switch, MCU and other components, supporting GPS-L1+BDS-B1perhaps BDS-B1+GLONASS-L1Frequency point four-array element broadband anti-interference function.
The main functions of the anti-interference antenna are as follows:
A) BDS-B1,GPS-L1And GLONASS-L1Satellite signal;
B) Up to three incoming GPS-L1 can be inhibited1+BDS-B1perhaps BDS-B1+GLONASS-L1Frequency band harmonic, sweep, pulse, white noise, frequency modulation, amplitude modulation, phase modulation and other broadband, narrowband and other types of interference;
C) Can receive external input control instructions, with controlled direct through function;
D) Direct power access function;
