供应JNSGyro-4是世界第一台、也是唯一一台双频卫星测姿-CK365测控网

JNSGyro-4是世界第一台、也是唯一一台双频卫星测姿系统。如果您曾经怀疑过GPS测姿系统的可靠性，那是因为您使用了单频系统。86CM波长的双频接收机（而单频只有19CM）使JNSGyro-4成为世界上最可靠、最快速的测姿系统。JNSGyro-4实际上是把4台20-通道测绘级双频GPS (可选GLONASS)接收机内置在一个小盒子中 (11 x 9 x 13 cm)，并和4个天线连接。来自4个GPS天线的双频码和载波数据被用于计算三个方向的角度和三维位置，每秒计算20次。. The dual frequency CODe and carrier data from four antennas are processed to determine the three orientation angles and three dimensional position up to 20 times per second. JNSGyro-4也可以与外部的基准站配合，运行于RTK或DGPS模式，提供高精度的位置和速度。
