LRK (original) (raw)
La cinématique longue distance (Long Range Kinematic, en anglais ou LRK) est une technique de positionnement par satellites basée sur l'utilisation de mesures bi fréquence des ondes porteuses des signaux émis par le système GPS, GLONASS ou Galileo. Le LRK est capable de lever les ambiguïtés de phase jusque 40 km. Cette technique a été développée par Magellan Navigation (anciennement Thales).

| dbo:abstract | Long Range Kinematic (LRK) technology is a sophisticated kinematic method developed by Magellan (formerly Thales) Navigation that optimises the advantages of dual-frequency GPS operation. Other conventional methods use the dual-frequency only during initialisation. LRK makes solving ambiguities during initialisation easy and continuous dual-frequency kinematic operation possible at distances up to 40 kilometres. Conventional dual-frequency kinematic operation is limited to about 10 kilometres, using a combined observation on GPS L1 and L2 frequencies to produce an initial wide lane solution, ambiguous to around 86 centimetres. During a second phase, the conventional kinematic method uses measurements from the L1 frequency only. This method only allows for kinematic operation as long as the de-correlation of atmospheric errors is compatible with a pure phase single-frequency solution. Similar to the KART process, LRK is a simple and reliable method that allows any initialisation mode, from a static or fixed reference point, to On The Fly ambiguity resolution, when performing dual-frequency GPS positioning. LRK technology reduces initialisation times to a few seconds by efficiently using L2 measurements in every mode of operation. LRK maintains optimal real-time positioning accuracy to within a centimetre at a range up to 40-50 kilometres, even with a reduced number of visible satellites.
