GlobalSat USB GPS Receiver
When I installed an HF APRS system in my mobile that includes full bi-directional messaging, the use of a computer in the form of my Toshiba netbook was in order.
I then required a GPS receiver that connected to my netbook to allow for positioning reports when beaconing.
After checking out the various options available to me, I selected the Model BU-353S4.GlobalSat BU353-S4 SiRF Star IV USB GPS Receiver
This USB GPS receiver features a highly sensitive, low power consumption chipset in a ultra compact form factor as noted in my photo where I have it mounted on my radio stack.
The BU-353-S4 is powered by a SiRF Star IV GPS chipset, and provides superior performance in the canyons and valleys of the Rockies as well as in dense foliage.
With the SiRF CGEE (Client Generated Extended Ephemeris) technology, this GPS receiver has the capability of predicting satellite positions for up to 3 days in advance, and will deliver a CGEE-start time of less than 15 seconds under most conditions without any network assistance.
The bu-353-S4's MicroPower mode allows the receiver to stay in a hot start-like condition almost continuously while consuming very little power.
It is proving to be a terrific GPS receiver as part of my HF APRS messaging system.
