Compatibility Considerations The Quaternions to Euler Angles block is deprecated. Models built with the old block continue to be supported from an obsolete library that ships with the Aerospace Blockset software but is not visible in the Library Browser. Rotation Angles to Quaternions Block Replaces Euler Angles to Quaternions Block The Rotation Angles to Quaternions block converts spatial representation from any of 12 standard sequences of rotation angles to quaternions. Compatibility Considerations The Euler Angles to Quaternions block is deprecated. Models built with the old block continue to be supported from an obsolete library that ships with the Aerospace Blockset software but is not visible in the Library Browser. New Aerospace Blockset Demo The Aerospace Blockset product has a new demo, Design, Verification, Validation and Test of Satellite Flight Software, which illustrates how to use the Aerospace Blockset blocks to perform some to the steps of the design and verification of flight software for a satellite. Enhanced HL-20 Demo The HL-20 demo (aeroblk_HL20) control system has been enhanced. 15 Aerospace BlocksetTM Release Notes Version 2. 3 (R2007a) Aerospace Blockset This table summarizes what's new in Version 2. 3 (R2007a): New Features and Changes Yes Details below Version Compatibility Considerations Fixed Bugs and Known Problems Related Documentation at Web Site Printable Release Notes: PDF Current product documentation Bug Reports Yes--Details Includes fixes labeled as Compatibility Considerations, below. See also Summary. New features and changes introduced in this version are · "New MATLAB Animation Block" on page 16 · "New Pilot Joystick All Block" on page 16 · "WGS84 Gravity Model Block Modified" on page 16 · "New Aerospace Blockset Demo" on page 17 New MATLAB Animation Block The MATLAB Animation block creates a six-degrees-of-freedom animation of multiple bodies that have custom geometries. It is based on the Aero. Animation object. New Pilot Joystick All Block The Pilot Joystick All block provides a joystick interface on Windows® platforms. This block is the same as Pilot Joystick, but its Output configuration parameter is set by default to AllOutputs. It outputs six analog channels, buttons, and point of view indicators. WGS84 Gravity Model Block Modified The first input of the WGS84 Gravity Model block is now a three-signal vector that contains the position in geodetic latitude, longitude, and altitude. The 16 Version 2. 3 (R2007a) Aerospace BlocksetTM second optional input is now a scalar that contains the manually-specified Julian centuries. The WGS84 Gravity Model block also has new output coordinates and dimensions to output the gravity vector in NED coordinates. Compatibility Considerations The old WGS84 Gravity Model block is deprecated. Models built with the old block continue to be supported from an obsolete library that ships with the Aerospace Blockset product but is not visible in the Library Browser. To use the new version of the WGS84 Gravity Model block, you must replace the old WGS84 Gravity Model block from the Environment/Gravity library and reconnect the input to take into account the three-signal vector format. New Aerospace Blockset Demo The Aerospace Blockset product has a new demo, Multiple Unmanned Air Vehicles with Collaborative Control, which illustrates the use of the MATLAB Animation block. 17 Aerospace BlocksetTM Release Notes Version 2. 2 (R2006b) Aerospace Blockset This table summarizes what's new in Version 2. 2 (R2006b): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site Printable Release Notes: PDF Current product documentation New features and changes introduced in this version are described here. · "Aerospace Toolbox Product Replaces Control System Toolbox Product as Requirement for Aerospace Blockset Product" on page 18 · "Interpolate Matrix Blocks Modified" on page 19 · "Aerodynamic Forces and Moments Block Extended" on page 19 · "New Digital DATCOM Forces and Moments Block" on page 19 · "FlightGear Version 0. 9. 10 Is Supported by FlightGear Simulator Interface" on page 19 · "Pack net_fdm Packet for FlightGear Now Supports Code Generation" on page 20 · "New SimViewingDevice Block" on page 20 Aerospace Toolbox Product Replaces Control System Toolbox Product as Requirement for Aerospace Blockset Product The new Aerospace Toolbox product is now required to use the Aerospace Blockset software. See the Aerospace Toolbox User's Guide for more information. 18 Version 2. 2 (R2006b) Aerospace BlocksetTM The Control System Toolbox product is no longer required for the Aerospace Blockset product. It is recommended for certain applications and still required for certain blocks. Interpolate Matrix Blocks Modified The Interpolate Matrix(x), Interpolate Matrix(x, y), and Interpolate Matrix(x, y, z) blocks have been modified to accept the new Simulink Prelookup block output. You must now provide the interpolation index and interpolation fraction as separate input signals. [. . . ] If DCM equals eye(3) (identity matrix) and wind direction equals 0° (from North), the output of the Dryden Wind Turbulence Model (Continuous +q -r) block yields the same results as past versions of the Dryden Wind Turbulence Model (Aerospace Blockset Software Version 1. 0 and 1. 0. 1) with approximately 10-7 error. Also, for the Dryden Wind Turbulence Model (Continuous) block, the military specifications result in the same transfer function after evaluating the turbulence scale lengths, and the turbulence transfer functions balance each other out. When using metric units, values will differ from the previous version of the Aerospace Blockset product at the second decimal place (0. 0x) due to corrections in the metric altitude to measure wind speed. The specification calls for 20 feet and the new metric altitude is the exact conversion. [. . . ]
