Yesterday we performed a fit check of PicSat in the QuadPack CubeSat dispenser (on the right).
The dispenser and PicSat will be ship separatly to India where we will put PicSat in the dispenser before the integration on the launch vehicle.
This test allows to avoid discomfiture on the launch pad in case of an external modification of the satellite which may block it in the deployer. For this test, PicSat was almost in flight configuration with a development detector which will be modified in the next days.
Some news on PicSat !
We just receive the mechanical parts of the Payload, the next step is the coating to avoid lights reflection inside the telescope.
The avionics is also now integrated in the structure with body mounted solar panels, assembly of the deployables ones will occur soon !
We just finished the vibration test !
After an EMC problem detected once the first axis (Z) ran Friday (which perturbed the communication with the PC), we came back this morning to
perform X and Y.
Test went very well and the EMC problem was identified : the inductor of the shaker ! We just put the electric gain of the vibration device off and electronic test was good: temperature regulation, photodiode and piezo-stage check were OK !
Once back in LESIA, we disassembled the payload and put it on our bench to check the optical alignment with a simulated stellar source:
The first obtained PSF is nice, we’ll check with detail but it seems like there is no modification before and after the test.
