Ellipse 2 Micro Series. GNSS and Geodesy Concepts. Neither the accuracy of 100 meters (SA On) nor the accuracy of 20 meters (SA Off) is enough for many civilian applications.
Since the inception of GPS, methods have been, and are still being, developed to reduce errors and enhance the accuracy, even with the implementation and presence of SA and partial availability of L2 (AS). Differential Mode Assume you have two receivers not too far from each other. The errors due to the satellite clock, the satellite orbit, the ionosphere, the troposphere and SA affect both receivers the same way and with the same magnitude. SBG Systems - Ellipse-E: Miniature INS. Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout - BNO055 ID: 2472 - $34.95. If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope and magnetometer into actual "3D space orientation"!
Orientation is a hard problem to solve. The sensor fusion algorithms (the secret sauce that blends accelerometer, magnetometer and gyroscope data into stable three-axis orientation output) can be mind-numbingly difficult to get right and implement on low cost real time systems. Bosch is the first company to get this right by taking a MEMS accelerometer, magnetometer and gyroscope and putting them on a single die with a high speed ARM Cortex-M0 based processor to digest all the sensor data, abstract the sensor fusion and real time requirements away, and spit out data you can use in quaternions, Euler angles or vectors.

PX4FLOW Smart Camera - PX4 Autopilot Project. PX4Flow is an optical flow smart camera (it provides the image for setup purposes, but it not designed to capture images like a webcam).
It has a native resolution of 752×480 pixels and calculates optical flow on a 4x binned and cropped area at 400 Hz, giving it a very high light sensitivity. Unlike many mouse sensors, it also works indoors and in low outdoor light conditions without the need for an illumination LED. It can be freely reprogrammed to do any other basic, efficient low-level computer vision task. 168 MHz Cortex M4F CPU (128 + 64 KB RAM) 752×480 MT9V034 image sensor, L3GD20 3D Gyro 16 mm M12 lens (IR block filter) Size 45.5 mm x 35mm Power consumption 115mA / 5V Where to Buy Setup Guides Specifications Image Quality and Output PX4FLOW is not designed as a camera, but does all processing on-chip.

Mpact cameras with optical image stabiliser - Find the best prices, information and user reviews. Canon EF-S Protocol and Electronic Follow Focus. Two years ago, I spoke with a film maker who told me about the problem of manual focusing with the video enabled Canon DSLRs.
As the focusing sensor works only when the camera’s mirror is down, when in video mode, with the mirror up, the camera switches into manual focusing mode, via the lens focusing ring. Several solutions exist on the market, but they mainly use mechanical links to deport the focus ring to more accessible place on the camera rig. Some electronic solutions exist, but they use the Camera’s USB input and the focusing speed is quite low. Quad position hold with mouse sensor (reproduced) You might remember this blog post by Marko Klein Berkenbusch on using a hacked mouse sensor for position control of a quad.
With some help from Marko himself, I've mostly repeated his results on a branch of ArduCopterNG and thought I should share how I did it as it's slightly different. Please note that this is not official ArduCopterNG code, there's no support or anything for it. The Hardware: MultiWii%20Connection%20diagram_v1.9. Crius All In One Pro Review : FPV Central.
With MultiWii 2.2 out and advanced features like waypoint navigation becoming really usable on this platform, versatile flight controllers become more and more important.
But is the Crius AIO Pro a solid choice, or should you keep your distance? Find out in our review after the break! When shopping for a MultiWii-compatible controller there is a lot to choose from. In the Atmel-based crowd the Crius AIO Pro stands out with it’s unusual use of mini Molex connectors and the large number of ports. This enables the controller to fit within the standard 50x50mm size that’s supported by most frames.
