Low temperature test of ground radio navigation equipment

The purpose of the low-temperature test is to determine the adaptability of military and civilian equipment for storage and operation under low-temperature conditions. Low temperature testing is mainly used to evaluate the impact of low temperature conditions on the safety, integrity and performance of equipment during storage, work and disassembly and assembly operations. The low-temperature test of ground radio navigation equipment can verify whether the product can be used safely and normally in low-temperature environments.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various navigation equipment and provides professional low-temperature environmental testing services for ground radio navigation equipment.

Ground radio navigation equipment is an integral part of the radio navigation system.
Ground equipment can be divided into three parts: heading beacon, glide beacon, pointing beacon or range finder. When the rangefinder is part of an instrument landing system, it is usually mounted on the glide beacon.

Low temperature storage test: detection → cooling → insulation → heating → recovery → detection
Low temperature working test: detection → cooling → temperature stabilization → power on → detection → heating → recovery → detection
Low temperature combination test: detection→cooling→insulation→heating→temperature stabilization→power on operation→detection→heating→recovery→detection
