 Integrity information Generation

 jamming Detection

 - Check condition or satellite signals
 - Conform integrity or satellite information
 - identify jamming signals of L1(1575.42 MHz),
   L2C(1227.60 MHz bandwidth
 - Check satellite heath satatus and integrity calculation by algorithm

 - Determine whethrer jamming algorithm
 - Disturbance spectrum display



 Disturbance Monitoring alarm(NOT,AM)

NPA Alarm 

  - Case of disturbances, Near wave function Case of disturbance. real-time wave function   - Auto alarm system in case of over the limit of NPA

  - jamming status NOTAM around airport

  - The main user warming alarm 

  - Alarm system base on the threshold suggested by ICAO
