Under timing, they only list the Venus638LPx-T, which is a older (2011 copyright on the datasheet) 65-channel receiver. The LTE-Lite documentation mentions 65 channels somewhere too, suggesting that the LTE-Lite started out using this chip. Under navigation receivers, Skytraq lists the newer (2013) Venus838FLPx with 167 channels. So I would assume that the Venus838LPx-T-L used in the LTE-Lite is the same 167-channel hardware with timing firmware, and that the LTE-Lite switched from the 638LPx-T to the 838LPx-T-L sometime during development. - Dave On Tue, Nov 25, 2014 at 5:12 PM, S.

Re: [time-nuts] LTE Lite SkyTraq chip info
Hi! Navspark has one board with Glonass (http://navspark.mybigcommerce.com/navspark-gl-arduino-compatible-development-board-with-gps-glonass/) and one board with Beidou (http://navspark.mybigcommerce.com/navspark-bd-arduino-compatible-development-board-with-gps-beidou/). Both use a Venus 8 engine. There is also a timming version (http://www.navspark.com.tw/blog/more-ns-t-programmable-frequency-testing) with a programmable frequency output. It has a LEON3 Sparc-V8 core and can be programmed with Arduino IDE. Edésio On Tue, Nov 25, 2014 at 10:29:19PM +, Poul-Henning Kamp wrote: In message 7da89.51b7dfcf.41a65...@aol.com, S.

Re: [time-nuts] LTE Lite SkyTraq chip info
Said Really did not run it very long a few hours. In that time it ran fine and on Vista no less. Now thats scary. The fact that it had my location and insists on Asia along with fixed screen scaling hints that its half beaked. But there was little additional value compared to ublox accept for one thing I noticed. On ublox the update to the C/N updates every other second same with other screens. Then blanks the screen and repeats. A bit annoying. PUTTY isn't pretty but has what I care about. The offset. Regards Paul WB8TSL On Tue, Nov 25, 2014 at 5:12 PM, S.

Re: [time-nuts] LTE Lite SkyTraq chip info
Hi I think it’s more a supply and demand thing right now. There are a lot of systems (CDMA for example) that run on GPS time. There do not seem to be quite as many people putting out spec’s for the other systems (yet).
