Is there any change in satellites during these days?

My GPS can't fix (GPS chipset is mstar), while another seems to work good
(SiRF). What about all of you?

Hello, it's a problem in mstar chipsets.

You're right, my GPS chipset is Mstar! How is it possible? Reading all
around web they say it's caused by a reconfiguration of the satellites began
some days ago.. do you anything about it? Why does it influence Mstar but no
SiRF or other GPS?

Yes, it's a bug. The week of 14" of June it's the week 1536 from the
beggining of the count of the weeks on the gps system -> January 6,
1980. 1536 its 1024+512, from what I read from chinese sites
(translated by Google) they were using 9 bits to store the date
because these chipsets were developed after week 1024 -> August 8,
1999 (there were some problems in this date too). 9 bits can go till
512, so in this week it went to zero. I just don't understand why it's
working now... This week the gps should be obtaining the date of the
week August 15, 1999, but it's not, it's getting a date in the year
2089 (at least mine is)...


A semana de 14 de Junho foi a semana 1536 do início do
sistema GPS (6 de Janeiro de 1980) 1536-1024=512. Os gps mais
recentes baratuchos que só usavam 9 bits lixaram-se, já tás a perceber
né?
