| As a point the BT-318 is an up to 80metres and we have the GR-230 with 12 months warranty retailed at $100AUD. We are working on our prices now so that they are reasonable, however, be aware that because we have to pay duty and GST it makes it difficult to compete on an equal basis. If anyone needs a particular GPS that we don't display let us know and we will assist where possible. |

Hi,
Might just be time to refresh this old topic.
I hear that SiRF IV receivers with recent firmware output pseudorange and carrier phase, as well as a message MID64.2 with other very interesting statistics:

I have started a little discussion on my Blog and it would be great to have some feedback from people in this forum too.
If this is true, SiRF joins again after 6 years the group of low-cost carrier phase enabled receiver manufacturers where Skytraq (S1315F-RAW), uBlox (LEA-4T, LEA-5T, LEA-6T), and uNav (Fastrax IT03) rule.
Cheers,
Michele

Hi Michele,
I had seen that on your blog already, it's just a pity that there are no consumer bluetooth units with the chip in yet. I had heard (probably on these forums) that Sirf smooth the pseudorange using the carrier phase rather than giving you the raw data. Do you know if this is still true with the Sirfstar IV? |

Hi Hurston,
Making a BT unit shouldn't be difficult... the only tricky thing is the way GSD4e starts and stops, which requires a bit of logic on the host side (the BT receiver before shutting down should shut down the GPS rx as well with a pulse on the ON_OFF line), as well as the 1.8V levels on the ouptuts.
I have prepared a couple of USB designs (Navman and OriginGPS) with a push button and a couple of dual designs (Skytraq and OriginGPS) and I will send them to production this week to test how SiRF carrier phase works with RTKLIB compared to Skytraq.. (I did in the past a little parser from SiRF binary to Rinex so that shouldn't take too long).
Prices of GSD4e and S1315F-RAW compare, whereas uBlox LEA-6T is still at about 60EUR (x3 more) a piece in small quantities.
Greetings,
Michele

Which receivers provide raw data (pseudorange) ?
