No fix Micro-Mini MN5010HS

I’m sorry A1ronzo but we tried all of that and it still didnt work. We have a 3.3v regulated supply and we tried getting a lock on top of a 4 story parking lot on a cloudless night. Also it was just plugged into a normal breadboard sitting on the car hood…

We ended up settling with a EM-408 with an “Antenna GPS 3V Magnetic Mount SMA” as it is called here and it worked GREAT! Also the extra antenna was not needed but did help alot.

You had the antenna on the horizontal axis didn’t you?

23

um we had the micro-mini board point towards the sky and tipped it over to the horizon too. Either way if it is truely that sensitive then it would be useless to our project at the least.

Hi everyone,

I just received my Micro-Mini MN5010HS and I feel I run into the same problem :frowning: I pluged it to a [Breakout Board for FT232RL USB to Serial (GND, TX, RX and 3.3V connected) and plugged the USB to my PC. The serial communications are ok, but I get no fix. The led on the Micro-Mini MN5010HS never comes up.

I’ve tried during 2 hours, tried it indoor and outdoor, horizontally and vertically with no results.

I don’t know if there are less or more GPS sattelite cruising above France (where I live and where I made my tests) than above Florida, but my car GPS works without any problem.

I’m not sure I understood what should be grounded. Anyway, I don’t think I’ll try to solder anything on the board as I may return it to Sparkfun.

Have you any idea ?

Thanks for any answer.

Sincerely,

Hello,

I let my Micro-Mini MN5010HS scanning for one night and finally, after twelve hours, it found enough satellites (up to 9 satellites) to get position data. Unfortunately, when I move it even very slightly, it looses its synchronisation. In fact, it seems to work only on a certain position (the component side of the PCB faced to the ground with an angle of 45 degrees to the horizontal and with a south-west orientation). In this configuration it does not meet my project’s need at all: I wanted to embed it in a UAV…

Is it possible to ask for a return and exchange for another Micro-Mini MN5010HS or maybe for a EM406A or EM408 that seems to be higher sensitivity ?

Sincerely,

Remi

I retried my Micro-Mini MN5010HS in the same position as in my previous test and it doesn’t get position information. Sometimes it reports me 1 satellite in view but that’s all. It definitively seems to have a problem :cry: . I’ve asked the technical support to return it.

Sincerely,

Remi

Perhaps it’s the Bermuda Triangle. :slight_smile:

hmmm good reference.

:smiley: :smiley:

here where im at its more like Manchurian Global Inc.

:wink: :wink: :wink:

A1ronzo:
Hello everyone.

If you still are having issues, there could be environmental factors that are causing interference.

yah make sure nobody is using an LRAD around you, and make sure nobody is using CW jammers hahahahahah.

Manchurian Global Inc. right here.

im serious.

29

and no not the one with sinatra (although sinatra was god)…

im talking the 2nd one…

“in the dark… in the desert… under fire…”

yah that Manchurian global.

:wink: :wink:

30

hey is it still the bermuda triangle??

all my gps boards are working hahahah. even my custom ones.

still manchurian global here. no change on that.

Hi,

I returned my Micro-Mini MN5010HS to SparkFun and they tested it and they confirmed that there were a problem. I ordered an EM-408 instead. I received it yesterday but I didn’t have time to test it yet. I’ll tell you as soon I’ve tested it.

32

ive had the em 408, its a nice unit…

stable.

33

I have just received this unit as a replacement for a 406A in a project I’m working on. I couldn’t get a lock full stop yesterday, but have succeeded today after about 20 mins. However as soon as I moved the device it lost it again. Not ideal for a moving application.

Although the 406A is bigger, once locked, the device can be brought inside with no loss of signal.

Real shame these don’t work as the size of the unit is very impressive.

34

try the venus??

looks like a winner.

35

Jason mentions an active antenna below. Which one are you talking about ? We can’t get a fix either. Has this product been improved since these last postings?

thanks

Beatriz,

The product mentioned in this thread is not my own. The OP is referring to a product sold by SparkFun. My mention earlier was of a product that I produce and contains the MN5010HS GPS module.

37

I’ve have abeen trying to use a couple of the GPS Micro-Mini modules ( GPS-08936 ).

Was able to get a fix from one of them about a week ago, but for the past several days I’ve been unable to get any fix data no matter how long I leave it running. (One is brand new and no fix data from it yet.) The units run ok and output serial data, just no data with a gps fix.

Blue sky, no obstacles, and a smooth 4.5V supply. Other brands of gps I’m using work fine.

I see that several people have posted this problem in the past, some people quite some time ago.

I’m wondering, has anyone figured out what I might be doing wrong? (I believe I have read all the past posts and found no clue that are of any help.)

I’d appreciate any suggestions of things that may have worked for you.

Thanks.

Glenn
