Mysle, ze wiekszosc osob tutaj spotkalo sie juz z technologia InstantFix - czyli sciagania danych z sieci, aby odbiornik zlapal pierwszego
fixa. Co ciekawe pojawilo sie wlasnie info, ze SiRF pracuje nad wersja nazywana na razie Instant Fix II, ktora nie bedzie wymagala sciagania
danych przez internet.
SiRFInstantFixII uses patent-pending algorithms that enable the PND to model the behavior of visible GPS satellites during the day and predict their position in the sky (the so-called “ephemeris” in GPS jargon) for up to three days in the future. SiRFInstantFixII continuously refines its calculations based on the latest data it receives from the satellites being tracked every time the PND is used. It performs these calculations completely autonomously, without ever needing updates of any kind from a network.
