There seems to be no technical data about this rx all over the internet. So I took the papers I got with my rx and here you can see the result. Here are details of the used data format.
Sometimes I'm in doubt about the English they used, but I wrote it down 'as it is'.
Simultaneously, by receiving up to 8 satellites parallelly and by making position to employ information of all received satellites (all-in-view positioning technology), it is possible to attain high accuray positioning.
Even if three satellites which are normaly necessary for positioning are not received, with two satellite reception, it is possible to make positioning where short time blockage of satellites.
With intake of GPS satellite correction data which is generated at the reference station, it is possible to make high accuracy postioning drastically.
It is 40% down-sized than the previous model. to save associate materials for integration and improve reliability, it can be installed on the Customer's board, which does not require pin connector and connection cable. With direct antenna connection to the receiver unit, inner antenna coaxial cable together with connector is not required anymore.
By containing the receiver board in the aluminium box, it minimizes its electro-magnetic generation.
