No. 48 - Latest Operational Update
For the rest, Smart-1 operation has been nominal during the reporting period.
The RF compatibility tests for the ranging tone tests with the Chinese CLTC and India ISRO have been completed. The tests were complemented with two specific tests using ESA ground stations: Maspalomas with Cortex and Redu with Enertec. Both stations provided and excellent support although only the Cortex tests were successful.
In addition an image of Crater Billy was released during this period and additional images are anticipated during the next reporting period.
Future activities are focused on the following:
- End of mission preparation and impact on the moon analysis
- Tone ranging test on Smart-1 with Chinese CLTC Kashi station and with ISRO
- Continue the work for the ground automation activities
The spacecraft status is good with all functions working nominally.
The AOC subsystem has done well in the period covered by this report. The ST CHUs have both worked within their temperature operational limits (19 °C).
The performance of the TTC subsystem has been nominal during this period.
EP, Power and Thermal
The performance of the Power and Thermal Subsystems during the reporting period was very good.
