History
The i-Blue 747 is a Bluetooth GPS data logger from Transystem Inc., a Taiwanese maker of small GPS devices and RF communication products, built around a MediaTek MT-3318 GPS chipset. It was followed by later 747-series models (747A+, 747ProS) from the same maker.
Where it is used
Exported by the logger's companion software (and by third-party tools such as BT747) when reading a recorded track off the device.
Structure
A CSV file with a fixed header line ("INDEX,RCR,DATE,TIME,VALID,LATITUDE,N/S,LONGITUDE,E/W,HEIGHT,SPEED,HEADING,DISTANCE,"), followed by one row per fix; only rows with a GPS fix type of "SPS" or "DGPS" are treated as valid positions. Per GPSBabel's own documentation of the same format, the logged height is the sum of height above sea level and the geoid-to-WGS84 offset, not a pure ellipsoidal height.
How widespread
The i-Blue 747 itself is an older, GPS-logger-era device; files in this format typically come from that device or a same-era 747-series successor rather than from a currently-sold product.
