The Indian Space Research Organisation (ISRO) on Thursday, January 25, mentioned that the 6-metre lengthy magnetometer boom on the Aditya-L1 satellite tv for pc has been successfully deployed.
The house company mentioned that the magnetometer boom was deployed in the Halo orbit on the Lagrange level L-1, on January 11, 2024. The boom had been in stowed situation for 132 days for the reason that Aditya-L1 launch.
ISRO mentioned that the boom carries two state-of-the-art, high-accuracy fluxgate magnetometer sensors that measure the low depth interplanetary magnetic area in house.
“The sensors are deployed at distances of three and six metres from the spacecraft body. Mounting them at these distances minimises the impact of the spacecraft-generated magnetic field on measurements, and using two of them assists precise estimation of this influence. The dual sensor system facilitates cancelling out the spacecraft’s magnetic influence,” ISRO mentioned.
The boom segments are constructed from carbon fibre bolstered polymer and function interfaces for the sensor mounting and mechanism parts.
The articulated boom mechanism includes 5 segments interconnected by way of spring-driven hinge mechanisms, permitting for folding and deploying actions.
“The deployment occurs in an accordion fashion, controlled by a novel patented Kevlar closed control loop mechanism, with hinges locking the segments into the deployed configuration,” ISRO mentioned.
It added that throughout the stowed situation, the boom is securely held in place by two hold-downs, transferring launch hundreds to the spacecraft physique.
A thermal cutter-based launch system is employed to execute the boom deployment on command.
“Data received through the telemetry switches confirm the hold-down release, first motion, and locking of all hinges. The observed in-orbit deployment time was approximately 9 s, well within the predicted range of 8 to 12 s. All telemetry indications for hinge locking and hold-down release were within nominal parameters,” it added.
India’s maiden photo voltaic mission Aditya-L1 reached the L1 level on January 6, 127 days after it was launched on September 2, 2023. The level is situated roughly 1.5 million km from earth and permits the spacecraft to view the solar constantly
