Good things take longer..

Well it is taking longer than we wanted, but the result will be an excellent transmitter unit!  The ST900e represents the ultimate tracker.  With 3D Position indication, G forces, Barometric altitude, super accurate temperature, and an excellent GPS with omnidirectional antenna!  The radio options are amazing also - allowing any of 3 different types of radios to be used from Zigbee to 1 watt native support (no adpater board).

Did I mention it also records, and has some new modes that are really interesting?

  • Bump mode - uses the accelerometer to detect movement, and only sends a position updat if the unit is moving.
  • Static threshold - set the GPS to only report new position data if moving - avoids 'wandering' while sitting still
  • Short sentence - allows the unit to send short position only sentences to increase speed or density of the network

So, it is a really cool sensor.

Problem is that it is also REALLY COMPLEX.  Our ace firmware designer is hard at work with only a few final items to wrap up before our final spin, then we'll be ready.  Our current challenge is the SCP1000 sensor. The folks from VTI are being very helpful with this, and when done, you will be able to see very minute changes in altitude very accurately.

As you can see above, the SCP1000 is SUPER SENSITIVE!  Able to show the difference of just a foot in real time.  This is a much better way to determine altitude than using a GPS for short term altitude readings because GPS vertical accuracy is considered very good if it provides 25ft of accuracy, and most are plus or minus 100 feet vertically or more.

So, probably a 3 week slip here, sorry folks, but you want us to put in the extra hours for a quality product!
