アブストラクト
The BAN (Burst Alert Network) is comprised by an equatorial belt of VHF receiving stations dedicated to relaying via the internet HETE burst alerts and spacecraft status reports to the MIT Operations Center. Messages created by the satellite are sent to the GCN within seconds. Each of the 14 BAN stations consists of low cost (total is less than $3000) components: a simple antenna, a preamplifier, a PC, and a receiver. HETE broadcasts a repeated VHF message stream to minimize the data corruption due to low signal level and varying local noise conditions. This low technology approach has proven to be successful for HETE operations. Real time coverage of the satellite has steadily increased from the time of the launch in 2000 to a value near 80% in 2002.
