Sure, but you're in the wrong newsgroup. Try:
alt.satellite.gps
sci.geo.satellite-nav

You don't need Wi-Fi speeds to transfer 4800 baud GPS data.
I would look into one of the 433Mhz, 915MHz, or 2.4Ghz wireless links
that offer serial port connectivity. Since you're in Israel, you'll
need to check which frequencies and equipment are legal to use.
900meters is too far for Bluetooth, so that's not going to work.
Start with:

There are plenty more, but this should give you an idea of what's
available. Search for Google "RS-232 wireless" or "RS-232 radio
modem".
I also blundered across wireless rs-232 kits made for robotics.
