Galileo primera Transmisión

Ayer, 7 de Mayo, el GIOVE-B (Galileo In Orbit Validation Element - B) ha transmitido sus primeras señales.

“Now with GIOVE-B broadcasting its highly accurate signal in space we have a true representation of what Galileo will offer to provide the most advanced satellite positioning services, while ensuring compatibility and interoperability with GPS”, said Galileo Project Manager, Javier Benedicto.

El 32 no es trigo limpio

Con la puesta en orbita de un nuevo satélite PRN32, la constelación GPS se ha incrementado a 32 satélites, mejorando la precisión y cobertura, pero desde el USCG Navigation Center, avisan que para los receptores con sus añitos el invento no es compatible.

On February 27th, 2008 the GPS constellation increased to 32 satellites (PRN 32) thus providing a 5% increase in satellite availability and DOP (dilution of precision) world wide. It has come to our attention that some GPS equipment—particularly old equipment which is non-compliant with the GPS interface standard (IS-GPS-200)—cannot recognize this additional satellite and subsequently are unable to calculate a position (see listing below).
