Development Data Logger Software For Thermal and Power Identification Of LAPAN-A4 Satellite Camera

Abstract

The process of testing and verification of satellite components is important to ensure that each sub-system can complete the task that has been designed. Thermal monitoring is important for the camera, therefore thermal measurement has to be accurate because changes in temperature can cause data error. Besides thermal, power requirements are one of the most important parameters in satellite development. This paper aims to conduct thermal and power testing from a data logger. The data logger which is an instrument to read data from time to time. From the test data, it can be seen that the ADC, PCB and Charge Coupled Device temperature at each Image Interface Modules will increase drastically when the camera is on the operation mode. The temperature at each Image Interface Modules increases for about 11.41° C, 13.61° C, 8.21° C and 7.81° C for ADC, PCB, Charge-Coupled Device channel 0 and Charge Coupled Device channel 1 respectively. Barrel temperature does not change significantly when the camera is turned on. Barrel temperature at each Image Interface Modules changes in the range 23C − 24C according to ambient temperature. For power consumption based on line period testing with line period mode using an altitude range of 485 km − 700 km. The initial power needed at an altitude of 485 km is 18.77 W. The power required at the simulation of 700 km altitude is 16.17 W.
