The SP-7 contains a MEMS based three-axis gyroscopic device (strapdown gyroscope) and a three-axis accelerometer. Using advanced software algorithms, the measurement data from these sensors is fused together with other information as may be available via the interfaces to provide a best estimate AHRS solution.
The SP-7 typically provides bank and pitch angle, rate of turn, as well as gravitational forces or acceleration to the host system.
Using a newly developed dynamic aiding algorithm, the SP-7 is able to provide outstanding resilience to performance degrading effects caused by vibration and airframe shocks while avoiding negative affects of traditional aided systems.
The SP-7 AHRS provides measurement of angular rates up to 250 degrees per second on any axis and measures G-forces up to 6 G.
The SP-7 forms an ideal companion product to MGL's EFIS systems but can also be used stand-alone with certain Blaze or Vega instruments.
The SP-7 provides several interfacing options: The reliable CAN bus is used with iEFIS exclusively. On older Odyssey and Voyager systems you can use either CAN bus or the older MGL Airtalk link (CAN bus is recommended due to higher performance). Finally, the SP-7 provides a traditional RS232 serial interface at 57600 Baud intended for simple third party use as well as for Firmware updates.
SP-7 devices manufactured after September 2013 can also receive firmware upgrades through the CAN interface via iEFIS systems. Older SP-7 systems can be upgraded to current firmware versions using the Windows based update utility available for download on this page.
