The Handbook is maintained in a modular format to provide interface design data to flight projects using the DSN. Modules are updated as appropriate. Each member product in the PDS collection is the set of modules as they applied at that point in time. Modules include: 001 Handbook Introduction 101 70-m Subnet Telecommunications Interfaces 102 26-m Subnet Telecommunications Interfaces (omitted in 2009 and later versions) 103 34-m HEF Subnet Telecommunications Interfaces 104 34-m BWG Antennas Telecommunications Interfaces 105 Atmospheric and Environmental Effects 106 Solar Corona and Solar Wind Effects 107 Radio Source Catalog 201 Frequency and Channel Assignments 202 34-m and 70-m Doppler 203 Sequential Ranging 205 Command Service 206 Telemetry General Information 207 34-m and 70-m Telemetry Reception 208 Telemetry Data Decoding 209 Open-Loop Radio Science 210 Delta Differrential One-way Ranging 211 Wideband Very Long Baseline Interferometry 214 Pseudonoise and Regenerative Ranging 301 Coverage and Geometry 302 Antenna Positioning 303 Media Calibration 304 Frequency and Timing 305 Test Support 901 Handbook Glossary urn:nasa:pds:context:facility:observatory.dsn telescope_to_facility This context product provides more information on the NASA Deep Space Network as a whole. urn:nasa:pds:context:facility:observatory.madrid telescope_to_facility This context product provides more information on the Madrid Deep Space Communications Complex. urn:nasa:pds:context:instrument:dsn.rss telescope_to_instrument This context product provides more information on the commanding, radio tracking, and radio science instrumentation at the telescope. https://www.mdscc.nasa.gov/index.php/en/history/ An overview of the Madrid Deep Space Communications Complex with photographs. Pull down the Antennas menu and select "DSS 55" for information about this antenna. 34 355.747367 40.424296 819.061 WGS 84 Ellipsoid Deep Space Station 55 (DSS-55) became operational in 2003. The antenna is very similar in structure to earlier 34-m DSN antennas; however the transmission and reception equipment is located underground rather than in a cone at the focal point of the dish. The radio signal is guided from the subreflector through a hole in the surface of the dish to the receiving equipment via a system of reflecting mirrors inside a large tube. The reverse path allows transmission. This 'beam waveguide' (BWG) design reduces weight on the reflecting surface, insulates electronics from environmental factors including dish movement, and simplifies maintenance. DSS-55 can transmit up to 20 kW at 7.1 GHz; it is expected to have an 800 W transmitter at 34.5 GHz by late 2024. It can receive simultaneous right- and left-circularly polarized signals at 8.4 and 32.0 GHz. Antenna coordinates were converted from Table 5 in module 301 (revision L) of the DSN Telecommunications Link Design Handbook (DSN document 810-005). The Madrid Deep Space Communications Complex (MDSCC) has been managed since December 2012 by Ingeniería de Sistemas para la Defensa de España. MDSCC is located about 65 km west of Madrid, near the town of Robledo de Chevala, Spain.
