LOC record

The LOC record is expressed in a master file in the following format: LOC ( d1 [m1 [s1 {"N"|"S"} d2 [m2 [s2 {"E"|"W"} alt["m"] [siz["m"] [hp["m"] [vp["m" ) (The parentheses are used for multi-line data as specified in RFC 1035, section 5.1.) where: d1: [0 .. 90] (degrees latitude) d2: [0 .. 180] (degrees longitude) m1, m2: [0 .. 59] (minutes latitude/longitude) s1, s2: [0 .. 59.999] (seconds latitude/longitude) alt: [-100000.00 .. 42849672.95] BY .01 (altitude in meters) siz, hp, vp: [0 .. 90000000.00] (size/precision in meters) == An example DNS LOC resource record ==

• statdns.net for the coordinates: {{sxhl| statdns.net. IN LOC 52 22 23.000 N 4 53 32.000 E -2.00m 0.00m 10000m 10m == Altitude for Geosynchronous Earth Satellites ==

The altitude range provides the following: • DNS altitude range [-100000.00 .. 42849672.95]. This range can be easily stored in 4 bytes. • Maximum altitude is 42,849.67295 km. Which is large enough to store the altitude of a circular geosynchronous orbit (i.e. approximately 35,790 km above mean sea level). • Maximum depth of 100 km below earth surface (approximated by the WGS84 reference ellipsoid). == See also ==
