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.

  • Automatic Measurement of Rf Signal Spatial Properties and Antenna Patterns
    AUTOMATIC MEASUREMENT OF RF SIGNAL SPATIAL PROPERTIES AND ANTENNA PATTERNS Ing. Michal VAVRDA, Doctoral Degree Programme (2) Dept. of Radio Electronics, FEEC, BUT E-mail: [email protected] Ing. Ivo HERTL, Doctoral Degree Programme (2) Dept. of Radio Electronics, FEEC, BUT E-mail: [email protected] Supervised by: Dr. Zdeněk Nováček ABSTRACT Radio frequency signal measurement site is described in the presented paper. It enables direction setting by antenna rotator and signal frequency scanning and consequently measuring the parameters using a receiver. The site has two basic uses: measuring of antenna pattern; scanning and locating of RF signal. The site and its operation are made universally, the accuracy depends of rotator quality and parameter amount depends of receiver type. 1 INTRODUCTION The current development in wireless communication requires powerful technologies for antenna testing and signal measuring. Sophisticated devices measure plenty signal parameters, but there is not simply site, which combines the use of these devices with antenna rotator system for measuring the spatial properties of signal also. In this work the site for scanning, locating and measuring of radio frequency signal and measuring and testing the spatial properties of antennas is designed. It consists of antenna system, antenna rotor, receiver and control unit (rotator controller, PC and operating software). The antenna system and receiver type both has to be chosen depending on the measuring conditions (service, frequency band, bandwidth, polarisation, etc.). The locating accuracy is increased with antenna directivity but the necessary number of measuring directions is also increased. The antenna rotor quality determines the accuracy of location.

  • 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.

The rotator is to have the capability to be manually controlled (press button switch) or software driven. It should incorporate safety stop switches as well as position and speed sensors in order to achieve smooth movement and correct stopping position. The basic principle needs to be studies are speed control using the microcontroller, exact angle of position movement, and stoppable motor can be done in time due to emergency cases. As larger load is applied to the device, the large inertia will need to be compensated to achieve a good dynamic.

  • 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.

  • C-Band TWG-1 Best Practices Annexes
    ANNEX D Approved June 4, 2020 Terrestrial-Satellite Coexistence During and After the C-Band Transition Technical Work Group #1 Scope of Work 1. Preventing Interference 1.1. Emphasize the need for the FCC to complete its review of the pending C-Band incumbent earth station registration and modification applications in IBFS. 1.2. Agree on relevant data necessary for protection of Earth stations. (All 3.7 GHz Service licensees need to work from a common list of Earth stations.) 1.3. Understand best practices that 3.7 GHz Service licensees use to predict whether the FCC- specified power flux density (PFD) limits will be exceeded at earth station locations. 1.4. Agree on a common method for converting between PFD and power spectral density (PSD) at the Earth station. 1.5. Understand the nature of the Earth station receive filters to ensure that they will be adequate to reject 3.7 GHz Service signals below 3.98 GHz over a range of environmental conditions in order to ensure that the FCC-specified blocking PFD limit is met. 2. Interference Detection 2.1. Develop a procedure for earth stations to positively identify or exclude sources of interference. This procedure should rapidly eliminate non-3.7 GHz Service causes and initiate the inter-service interference resolution process. Consider whether a detection and alerting mechanism could be automated, particularly for major Earth station facilities. 2.2. Develop estimates of distances between 3.7 GHz facilities and earth stations beyond which interference is unlikely. 2.3. Develop a process for positively identifying or excluding sources of 3.7 GHz interference.
