  • A highly reliable two-segment deployable boom has been developed and manufactured for the Double Star Program. Two spacecrafts, one for equatorial, the other for polar orbit are equipped each with two mechanisms. One boom deploys two flux-gate magnetometers, the other a search coil magnetometer. The paper discusses the structure and mechanical problems of TC-2 satellite’s exploring booms in technical state improving design, and analyzes the mode, structure static strength as well as the clamp expanding process of exploring boom in TC-2 satellite. Results show that the boom clamp’s frequency only had small change after altering the pyrotechnical rod cutter and it would not have influence on the satellite’s frequency. The improved clamp can bear dynamic load, and its maximal stress and strain are all within the allowed range of material. Moreover, the clamps do not intervene with other parts when they are deployed, which can meet the satellite’s request.
