Re: Initialization for nut4nt+

Not sure that all of GPIO are really usefull :roll:
But these four are!

Code: Select all

#define NT1065EN  (17)  /* GPIO17, CTL[0] */
#define VCTCXOEN  (19)  /* GPIO19, CTL[2] */
#define ANTLNAEN  (50)  /* GPIO50 */
#define ANTFEEDEN (18)  /* GPIO18, CTL[1] */

Re: GNSS Signals: GPS L1 and L2, GLONASS L1 and L2

The GPS data is too small to get any navigation information. Can you please share GPS L1, L2 and GLONASS L2 file with more details. Hello, vasub. Which files exactly are you talking about? I will check. The GPS L1, L2 and and GLONASS L2 file which is uploaded at https://drive.google.com/drive/folde...

Re: Strange behavior with Amungo Nut4nt

Dear Igor and Viktor, But where exactly can I find the last version of the AmungoFx3Dumper source code? I can only find it here (https://github.com/amungo/AmungoFx3Dumper), where in the main.cpp file (https://github.com/amungo/AmungoFx3Dumper/blob/master/src/main.cpp) there is still this patch: ......

Re: Strange behavior with Amungo Nut4nt

some libusb functions calls were commented, such as the one providing a START command with libusb_control_transfer, since it seems that the nt1065‎ doesn't need it (it is correct? In this case, when exactly it starts to transfer data? and stop it?). You should leave START command. It can be useable...

Re: Antenna array vs jamming

Hello! A day ago I've got a 'secret' Amungo's small antenna array. And I dumped 10 seconds of L1 GPS for you. It's about 10 seconds of signal and it's jammed only near the end (after 8th second at least). You can download signals from nut4nt+secretRA4_array from here: https://goo.gl/kXqlO6 I am goin...

Antenna array vs jamming

Hello! I've just make an experiment. I've got a RF generator to make a noise in L1. I used F = 1575MHz I connect nut4nt 4-channel board with RA4 antenna array and couldn't find a correlation when a generator is on. You can see a spectrum with synthetic noise (from a generator). 2016-12-24 18-42-52 F...

Re: Latest news from Crowd Supply campaign

Hello, guys!

The campaign has ended, but we've made about 35%
But there are two good news:
  1. We can server you orders anyway (just send us a letter)
  2. We will try another campaign in few months.
