GEM Series G3 - SD Card Data Logging
Data Logging Perfected
Utilizing the old data log files was difficult because the information was lacking. Oh there were plenty of temperatures all right, but without parameters like altitude, and airspeed some error prone assumptions had to be made to put all the pieces together.
The new G3 solves that problem. It incorporates not only its own measured data but data from the TAS-1000 air-data system and the GPS. Adding ambient data to the file facilitates meaningful comparisons of one flight to another. Another key benefit of these extensive data files will be in processing them to create airplane specific performance charts.
Unlimited Storage for Free
When we introduced the GEM 610 years ago 32 Kbytes was the largest available non-volatile memory chip. If ordinary techniques were used this is scarcely enough storage for an hour-long flight. Far from the 50-hour goal at first it seemed an insurmountable limitation.
Packing the instrument with dozens of expensive chips was impractical. A custom data compaction algorithm was developed that would pack more data in a small memory chip and shorten transmit time over the infrared interface.
Luckily to day none of this matters. Fueled by the digital camera revolution flash memory is so cheap it may as well be free.
We chose the SD card for its widespread availability and low cost.
Fortunately the card is small enough fit in the tiny space below the display.
The card has a Windows compatible file system with Excel compatible files so you can read it without any special software. The cards have huge capacity, large enough to store engines entire life history.
