CUTE1.7+APD-II ist im FM Packet Mode und sendet für 24 Stunden APD Sensor Daten.
We started a long-run (continuous 24hours) of the APD sensor at 11:30, Jun 3 (UTC) and it will be turned off on 11:30, Jun 4(UTC). During the APD is turned on, the APD status packet can be heard everywhere in the world. FM packets are transmitted on 437.475MHz and packet formats are available in the following web-page http://lss.mes.titech.ac.jp/ssp/cute1.7/fm_mode_apd_e.html.

For exapmle, according to an above APD status packet we can obtain
informations as;
4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A : Header(JQ1YTC>JQ1YCZ)

Hiroki Ashida: …thank you very much for your cooperation! We’re very pleased that the APD module looks working well. The status you received are correct. We’ll conduct observation from 2330UTC, these were a warm-up period for APD observation. So, we have not applied the HV(High-Voltage) to the APD module. I apologize for lack of information.
