Product overview

The Chongqing Tianjian Inertial Technology Co., Ltd. TY-INS30A inertial navigation device provides attitude measurement for low-cost aircraft. Its construction combines a MEMS gyroscope, MEMS accelerometer, power conversion circuit and high-performance navigation computer. Attitude computation algorithms support initial attitude alignment and high-precision measurement on moving platforms. The device includes self-test and static initial alignment functions, and communicates with a user terminal to deliver position, velocity and attitude in real time. Self-alignment takes ≤3s.

With external satellite navigation information, the TY-INS30A provides integrated navigation at 200Hz, with horizontal positioning accuracy of ≤8m RMS, altitude accuracy of ≤12m RMS and velocity measurement accuracy of ≤0.2m/s at 1σ. Its body measures 30mm×30mm×20mm and weighs ≤55g. Power comes from a nominal 5V DC supply, with a supported range of 5V±0.5V and steady-state consumption of ≤3W. Reverse polarity protection allows normal operation after an accidental reversed connection is disconnected and correct power is restored.
