Traditionally, the sighting of Es’hail brings happiness as it means that winter is coming and that good weather will soon be with us. We hope that the arrival of Es’hailSat will equally be beneficial for the satellite community.” (from Es’hailSat: Follow the star) Canopus /kəˈnoʊpəs is the brightest star in the southern constellation of Carina, and is located near the western edge of the constellation around 310 light-years from the Sun. Its proper name is generally considered to originate from the mythological Canopus, who was a navigator for Menelaus, king of Sparta.

  • The Future of Amateur Radio Satellites in the Cubesat
    The Future of Amateur Radio Satellites in the CubeSat Era The Radio Amateur Satellite Corporation (AMSAT) seeks to place an ongoing series of 3U or 6U satellites into highly elliptical orbits to provide long duration communications service to the worldwide amateur radio community. AMSAT's technical challenges in preparing a HEO satellite mission are very similar to what is required for Lunar or Interplanetary CubeSat missions, including harsh thermal and radiation environments, little or no magnetic field to torque against, and challenging communications links, which make this mission very different from the many LEO CubeSats that have been built and launched by other organizations. AMSAT is seeking partnerships with other organizations to demonstrate new technologies in High Earth Orbit, to carry low cost scientific instruments into HEO and to qualify for NASA sponsored launches into Geosynchronous Transfer Orbit or other high altitude orbits whenever such an opportunity occurs. Radio Amateurs have been building and launching small satellites for over 50 years. OSCAR-1 was launched on December 12, 1961 as a secondary payload on the Thor- Agena rocket that launched the US Air Force Discoverer-36 mission. OSCAR-1 was the first satellite to be deployed as a secondary payload from a launch vehicle. The bureaucratic efforts required to secure permission to launch OSCAR-1 greatly exceeded the effort required to build the satellite and established a precedent for all subsequent secondary payload launches of the past five decades. OSCAR stands for “Orbiting Satellite Carrying Amateur Radio”. Today many agencies, laboratories, universities and high schools are building and launching dozens of small satellites every year, but it all started with OSCAR-1 in 1961.

  • FCC FACT SHEET* Streamlining Licensing Procedures for Small Satellites Report and Order, IB Docket No
    FCC FACT SHEET* Streamlining Licensing Procedures for Small Satellites Report and Order, IB Docket No. 18-86 Background: The Commission’s part 25 satellite licensing rules, primarily used by commercial systems, group satellites into two general categories—geostationary-satellite orbit systems and non-geostationary-satellite orbit (NGSO) systems—for purposes of application processing. The Commission’s satellite licensing rules, in particular those applicable to commercial operations, were generally not developed with small satellite systems in mind, and uniformly impose fees and regulatory requirements appropriate to expensive, long-lived missions. However, the Commission has recognized that smaller, less expensive satellites, known colloquially as “small satellites” or “small sats,” have gained popularity among satellite operators, including for commercial operations. Therefore, in 2018, the Commission adopted a Notice of Proposed Rulemaking that proposed to develop a new authorization process tailored specifically to small satellite operations, keeping in mind efficient use of spectrum and mitigation of orbital debris. What the Report and Order Would Do: • Create an alternative, optional application process within part 25 of the Commission’s rules for small satellites. This streamlined process would be an addition to, and not replace, the existing processes for satellite authorization under parts 5 (experimental), 25, and 97 (amateur) of the Commission’s rules. • This new streamlined application process could be used by applicants for satellites and satellite systems meeting certain qualifying characteristics, such as: . 10 or fewer satellites under a single authorization. Total in-orbit lifetime of satellite(s) of six years or less. Maximum individual satellite wet mass of 180 kg. Propulsion capabilities or deployment below 600 km altitude.

Most have flown as piggyback payloads where excess payload capacity was not required. Many have flown as test payloads for new launch vehicles on their test flights. The Phase 3-D satellite is scheduled for launch in the second half of 1997 as the primary payload for the Ariane 502 launch vehicle. This paper will discuss the risks and tradeoffs associated with flying on an unproven launch vehicle, insurance issues, and past successes and failures for those 30 satellites. AMSAT has always relied on the kindness of the aerospace industry.
