Power Budget (examples)
The power budget has been estimated based on power consumption measurements of DATA-CUBE³ type 1
at laboratory conditions and on using two
“Duracell Procell MN1300” batteries with a capacity of 39.6Wh.

Please note that the real runtime in the field can vary and is strongly depend on different parameters like
environmental temperature, real capacity and age of batteries. Please see the battery capacity vs. temperature
diagram below to estimate the runtime of the DATA-CUBE³ Type 1
Battery capacity depending on temperature
for “Duracell Procell MN1300” alkaline batteries
Additionally, the values of F_TIME and GPS_TI should not be a multiple of 60. This can lead to undefined
behaviour for internal reasons.
