Fiber optic gyroscope VG103PT - is modified VG949P with embedded TMP36 - sensor of internal temperature.
Via additional contact it provides possibility for better modelling and data correction.

Due to the plastichousing the gyro interior is well isolated from variable ambient.
Upgraded assembling brings to the gyro better shock endurance

RECOMMENDATIONS AND PRECAUTIONS

1.	Do not deform housing
2.	Fragile components inside - no shocks, no drop
3.	It is recommended to use 2 diagonal screws with elastic washers for mounting
4.	Treat as electrostatic sensitive unit
5.	Is designed to be mounted inside water protected equipment
6.	Increased humidity shortens essentially lifetime
7.	Power must be off during connecting
8.	Soldering to contacts - by low-temperature solder
