AIS receiver with USB connector

Yes. I did play this RTL-SDR module and compared with my dongle. The sensitively of my module is much better that it as the RF front-end are specified designed for AIS channels.
Working on a similar module which support WiFi connections, few of them has been shipped out for trial. I hope it will soon been released.
Happy to hear any comments on it.

Thanks
I ordered one of your yesterday.
This morning, I got a notification to say that it is on its way.
Unfortunately, I'm off to the boat for a couple of weeks so I won't be able to play with it until I get back

When I get back, I'm keen to see if I can get it running under Android - with the appropriate connector/lead.
I run OpenCPN so once the correct driver is in place, OpenCPN should take care of displaying AIS.

I also run OpenCPN under Windows so I will test it out there.
I ALWAYS debug new hardware/software by starting with something that works.
We are right near the coast so AIS signals are plentiful.

I'll report back on this thread in about three weeks.
 
Before releasing the new WiFi version, I think its worthy to ask for some suggestions here. Any comments are welcome.
Generally, there are two ways for AIS receiver to send the messages through WiFi. Firstly, AIS receiver works as a wireless router and broadcast the AIS messages to each clients(could be mobiles, tablets or computers). Alternatively, AIS receiver is connected to a existing wireless router, and it will send messages to each clients through wireless router.
The main difference from the users' point of view is as below:
1, With the second option, all users can still access internet(or local network) through wireless router(AP), while using the first option users cannot access internet. Some customers say since they use it on the sea, there is no internet, so they don't care. But how about people use the module on land?
2, The advantage of the first option is all messages are send to each users directly, so it can be more quick and lower package error rate(PER, which means the message is useless). With 6 terminals(2 windows computer, 1 Mac book, 3 Android mobile/tablet) as the receivers, we tested he average PER(package error rate) for the first option is only 0.7% while 1.9% for the second option.
At this moment, I have some of my existing customers reply. It about half to half option.

I would tend to go for the second option as I use a 3G wifi modem that can connect to the internet while offshore while coastal cruising so would need both.
