SanoSat-1 in low power mode

11:26 UTC CW beacon am9npq 1111034e6?64

Data packets show the same values:

Packet Type         1            |  COM Temperature     -11     C   
Battery Voltage     3400    mV   |  Charging Current    0       mA  
Battery Temperature -11     C    |  Radiation           -15240  µSv/hr
Number of Resets    187          |  Antenna Deployed    YES  

19:00 UTC – SanoSat-1 went into low power mode. If the battery voltage is below 3.4 V, it goes to low power mode. In low power mode, it transmits 1 GFSK packet every 3 mins and sleeps for 3 mins.

20:36 UTC high elevation pass – initial TLEs are slowly becoming unusable.

SanoSat-1 is transmitting only GFSK packets (they all have the same content). The reset counter has gone up.

Packet Type         1            |  COM Temperature     -3      C   
Battery Voltage     3520    mV   |  Charging Current    0       mA  
Battery Temperature -7      C    |  Radiation           0       µSv/hr
Number of Resets    196          |  Antenna Deployed    YES     

22:07 UTC nothing heard anymore
