G0 GPS Module

December 28, 2015 Piotr Esden-Tempski

Just in time for the new year 1BitSquared releases a new GPS module named G0. It is designed to neatly fit on top of the Paparazzi UAV Elle0 Autopilot, that they released just a few weeks ago.

G0 features the UBlox Max-7Q chipset, a large ground plane and EMI shielding. Due to the large ground plane and optional side flaps it has good multipath and EMI rejection characteristics, making it a great device to be used on fully autonomous systems that need high precision and reliable GPS reception.

For more information visit the 1BitSquared G0 pre-order page.

Paparazzi V5.8 release

December 24, 2015 Piotr Esden-Tempski

Merry Christmas dear Paparazzians!

We are happy to announce the release of Paparazzi; v5.8, providing you with lots of new features and improvements!

Just to pick out a few:

ADS-B support
improved use of optic flow for velocity estimation
improved mavlink support
possibility to reduce RAM and Flash usage by compressing the sine table
this allowed us to add basic support for naze32, CC3D and CJMCU boards
flip mode for multicopters
INDI guidance loop
lots of improvements/additions for computer vision modules
high speed logging to SD Card via SPI
improve support for Bebop and add Bebop2
guided mode for rotorcrafts

For a detailed overview refer to the CHANGELOG. 🙂

If you are already using paparazzi with Git, to enjoy all improvements you can switch to this new version via:
git remote update && git checkout v5.8

If you are new to Paparazzi and want to join in flying with it, you can you can simply download a tarball or get the source code via:

git clone https://github.com/paparazzi/paparazzi.git -b v5.8

Lisa/S Nano Quadcopter featured on sUAS News

December 15, 2015 Piotr Esden-Tempski

In the light of the recent FAA registration limits, the great guys at sUAS News wrote an article featuring the Paparazzi UAV powered Lisa/S nano Quadcopter. This platform was developed by 1BitSquared in collaboration with the TU-Delft MAV lab team, provides all the autonomous capabilities while being way below the FAA regulated limits for registration. The Lisa/S nano Quadcopter weighs only 39g while the FAA requires all aircraft above 250g to be registred.

Check out their article for more information.

Multi-UAV flights for simultaneous meteorological measurements

December 4, 2015 Gautier Hattenberger 4 Comments

ENAC UAV Lab team and Meteo-France (CNRS-GAME and ENM) teams have spent several days at the Atmospheric Research Center of Lannemezan (in the south of France) in order to perform experiments for simultaneous meteorological measurements through multi-UAV flight.

This was part of a research project called VOLTIGE aimed at studying the formation of cloud and fog events. One of the planes is measuring the turbulence near the ground, a second plane is flying above the cloud or the fog with a radiation sensor and the last one is making a vertical profile of temperature, pressure and humidity up to 1500 meters AGL.

All the planes were controlled by Paparazzi UAV Apogee boards, with on-board logging on SD cards and navigation patterns triggered by sensors readings.

Elle0 Autopilot

December 1, 2015 Piotr Esden-Tempski

1BitSquared has released Elle0, a new Paparazzi UAV autopilot. Elle0 is the lowest cost autopilot developed specifically for use with the Paparazzi UAV framework. It was inspired by the Lisa/MX and Apogee autopilots and has been stripped down to the most essential features while preserving the flexibility that Paparazzi autopilots are famous for.

Here are some of the specs:

STM32F4 168MHz ARM Cortex-M4 microcontroller with FPU
- 1 Mbyte of Flash memory
- 192+4 Kbytes of SRAM including 64-Kbyte of CCM (core coupled memory) data RAM
- Cryptographic acceleration: hardware acceleration for AES 128, 192, 256, Triple DES, HASH (MD5, SHA-1), and HMAC
- True random number generator
3 axis gyroscope (connected over SPI for high speed sampling and low latency)
3 axis accelerometer (connected over SPI for high speed sampling and low latency)
3 axis magnetometer (connected over SPI for high speed sampling and low latency)
barometer (connected over dedicated SPI for low noise operation and low latency)
1 I2C auxilary sensor connection
2 TTL level serial ports for telemetry radio and GPS
2 serial input interfaces for remote control receivers (using Spektrum compatible JST connectors)
1 USB port for easy firmware upgrade
8 PWM outputs/inputs for servos or legacy PPM RC receivers
2 Analog inputs for system battery voltage and current measurement
CAN TX and RX lines are accessible

Mechanically Elle0 is designed around the 30.5mm M3 hole pattern, popularized by the Nano Quad community. But Elle0 can be used on more than just Nano Quads, it has everything on board to control anything from a small Quad through a big Octocopter to Airplanes or Helicopters. For an autonomous UAV you just need to add a GPS, Telemetry radio and maybe RC receivers. 😉

Apropos RC receivers, Elle0 provides two Spektrum Satellite compatible connectors. You don’t have to crimp special wires to connect your Spektrum Diversity setup to your autopilot anymore!

For more information check out our Wiki Page. 1BitSquared is offering Elle0 for Pre-Order in their store. Elle0 will start shipping early 2016.
