"After the release of the SD-501, the first SD GPS to be fully operational but that lacked on board memory, here comes the much anticipated SD-502, powered by a SiRFstarIII chipset and with 512Mb of memory onboard..."

"The techies at Globalsat have come up with yet another winner with the SD-502,There are some issues with the underlying technology, but the GPS itself is well designed and a lot of thought seems to have gone into how the receiver will be used. It uses a double helix antenna which is a little less sensitive than the normal patch antenna, but the helix is capable of picking up signals in any position making it more flexible.”

"Without any doudbt the tested Globalsat GPS products are very good products and will satisfy their buyers. Each one has its own buy group, depending upon the needs of user. If someone wants to use a GPS device at both PDA and Laptop, then the BT-338 or BC-337 are the best choices. If the connection interface is Secure Digital, then SD-502 is a perfect match."

"I found the Compact flash GPS excellent, with the external antenna (which allowed the use of the GPS with athermic windshields) the signal arrives at a sensitivity to the height of the same waitings most demanding. The GPS SD is very good in comparison to the other SD receivers which I have tested in the past. On the other hand, it is not as good aS the the compact flash and, it has a tendancy to loose signal in urban canyons."
