The PHOENIX satellite is a double CubeSat that is being developed at NCKU as a part of the
which is to deploy a network of CubeSats in a string-of-pearl configuration as depicted for multi-poin.
The PHOENIX mission is to fulfill the in-situ lower thermosphere measurement mission and to
measure solar EUV flux and the measurement of the solar EUV flux will augment the QB50 mission.
The task of the NCKU team is to design, assemble, integrate, test, and operate the PHOENIX double
CubeSat to accommodate the following payloads for atmospheric studies.
The INMS is science sensor unit provided by the QB50 coordinator, VKI, for in-situ measurements of
the ion and neutral particles as well as temperature distribution. The solar EUV sensors are developed,
fabricated, and tested at NCKU.
PHOENIX Beacon Format
The detail of PHOENIX beacon is in the following table.
|0||C0||Kiss(TNC) mode (frame end)|
|2-8||9C 86 96 AA 8E A6 E0||Destination address (NCKUGS)|
|9-15||9E 9C 60 62 A8 AE 61||Source address (ON01TW)|
|19||5C||Master frame count (counter)|
|20||5C||Virtual channel frame count (counter)|
|21||00||First header pointer|
|22-23||08 0A||Packet ID|
|24-26||DB DC 5C||Packet sequence control #because of kiss mode of TNC, the DB DC actually are C0, so the Packet sequence is C0 5C|
|27-28||00 12||Packet length (actually data length-1, and beacon data length is 19)|
|29||10||Spare (0) + TM source packet (001) + spare (0000)|
|30||03||Service type (beacon is 3)|
|31||19||Service subtype (beacon is 25)|
|32-36||1F FB 04 2A 00||Time|
|37||FE||SID (beacon is 254)|
|41||FF||3.3 bus current|
|42||EE||5 bus current|
|43||AB||Communication board temperature|
|44||FF||EPS board temperature|
|46-47||A5 F6||Packet error control|
|49||C0||Kiss(TNC) mode (frame end)|
