1.Reached the world advanced level
2.GPS Radiosonde
3.Digital technology

GZZ2-07 series radiosonde are -1, -2 in two models, September 1999 in large quantities of high-altitude meteorological observation site equipment., GZZ2-07-1-type sonde is the independent development, China's first anti-frequency interference with the radiosonde With dedicated ground demodulator, Can effectively overcome or reduce the impact of co-channel interference. The product obtained in the 2001 third prize of Shanghai Science and Technology Progress. ZZ2-07-2 type radiosonde be compatible with 701,701 A, 701C weather radar

These two products can replace GZZ2-05 type radiosonde, have a narrow spectrum, frequency drift is small, output power, the answer pulse stability, and dynamic operating voltage range, high-altitude release a high success rate and so on.
