I may need a new gps
I think it's time to get a new GPS receiver because I believe the technology is far better than my current one to acquire signal faster in the city and keep them in view. Feel free to let me know if I'm wrong.
I have an iBlue 737 BT-GPS from 2008 using a mkt 1 mt3301+mt3179 chipset. Yes, I know there are newer chipsets, but my main issue is how much faster can the newer gps systems acquire the satellites REALLY,not just marketing propaganda, and how well do they keep them in view.
One thing that bothered me a couple days ago that I never noticed before, because I'm rarely sitting in one spot in the car programming my software, is after an hour or so of no sat views or locks, all of a sudden 5 locks and 9 views, then 40min later 4 views, and 20 min later nothing. ( I was around a canyon of 6 story buildings.) the satellites seemed to basically move over me and kept on their way.
So will one of the newer gizmos significantly help me out? Here are the ones I'm looking at in order. Any input?
1/ Holux m215+. Seems to have the best tracking system using something extra called glonass in their tracking and a mtk II chipset.
2/ Canmore gt-730f(g). Also has the mtk II glonass chipset.
3/ qstarz by-q818x mtkii chipset
4/ globsat bu-353 USB sirfstar iv (the only thing that really has me interested in this is the cgee that can apparently look 3 days ahead to the approximate position of sats for faster start up times. The question is do other receivers have similar tech)
Also, if anyone knows, do these come with AGPS?
Hi Champak you should think about getting the sure electronics gps developement board. http://www.sureelectronics.net/goods.php?id=99 It uses an external gps antenna and is very good compared to the global-sat models. A-gps uses the cellular network to assist in getting data for sat position. Not available in standalone dongles. For the best signal place antenna on a flat metal surface with at least 18" around it and not within 12-16" of another antenna. That will give the ultimate ground plane for the gps receiver to work effectively. I do fleet tracking and have for the past 10 years, in my business GPS and sat lock are very crucial. Hope this helps SNO
+1 for SNO's gps pick...i got mine on his reccomendation.he is dead right the sure gps locks on fast and solid.ive still got the global sat ones and there rubbish in comparason
i am still waiting mine after a problem that there were on the shipping address....!
i ll receive it ( i hope ) this week.
Ok thanks, but why? What makes this so impressive, especially since I've never heard of this chipset or type of GPS before...not that I'm anywhere remotely an expert? What makes it better? Does it predict future orbits? What makes this lock better? Note, if I use this, it would be placed in a pretty inhospitable place, behind the glovebox. Will that board hold up there? How long is the pigtail for the receiver? Is it easy to find an extension for it if needed? What is the exact size of the receiver?
I know you don't have the answer to all these questions, but I need some insight. Thanks.
Well it doesn't use the military satellite system, it uses the alien gps system, much more accurate. Enough joking now for the facts. Like I said earlier I own bu-353 and bu-353-s4 as well as a couple other units and this is the only one that works perfectly and fast to lock. it has a channel capacity of 48 and reads from 12 at any given time. Has some small memory to store last position for a faster boot time. Gives you a choice of usb/serial/bluetooth. very low current draw. and cheap too 34.95 for this quality and an external antenna on a 3 meter cable, and yes you can add an extension using standard sma male-female cable. Hope that answers your questions. I guarantee you will not be disappointed. I would put in a project box if it will be exposed to metal and such behind the glovebox. SNO
As above,i will add that i mounted mine in the center console,in a small project box that cost mabee $10 fron a local electronics store.i had enough cable to run it all the way outside the truck and ive glued it just under the windscreen to .still have some cable to spare..i have however damaged the external antenna while buffing the trucks paint somehow...now i fitted a temp antenna i had here and for the past few weeks its been buried under my junk in the passenger side footwell and its still working beautifully..before with the 4 other types of gps i have here,a fix was only possible with line of sight from the sky to the antenna..
Sent from my GT-N8020
you Know on ebay you can find it cheaper i think.

Ok, I'll grab one. What size exactly is the receiver?
Bought it. $31.65. We'll see how it works out.
