+====== AIMMS ======
+{{:atmos:citation:instruments:aimms.jpg?300x200|AIMMS Probe}}
+  * Description: Aircraft-Integrated Meteorological Measurement System
+  * Manufacturer: Aventech Research Inc. ([[http://www.aventech.com/index.php?content=products&site=aimms20|Manufacturer Product Page]])
+===== Data =====
+==== Saving to USB stick on I/O Module ====
+Connect a computer to COM1 of the Data IO module and run a serial terminal program configured to 115200,N,8,1, and once you see the media has been mounted, type "o" from the keyboard to open the file, "c" to close.
+Files are opened and closed during the flight based on threshold speed on take-off and threshold speed on
+landing.
+==== Location & Format ====
+=== RAW Data ===
+  * Data Location: \\ /nas/ral/<LocationofProject>/<Season&Year>/Aircraft/<NameofAircraft>/FlightData/<DateofFlight>/AIMMSData
+  * Data Format: <Base#>.a<##> or <Base#>.r<##>
+      * .a is an ASCII File
+      * .r is a Binary File
+         * Flight data is broken up into pieces \\ (Example: 03200748.a00 03200748.a01)
+  * Combined Data Format: <Base#>.aim or <Base#>.raw
+      * aim is an ASCII File
+      * raw is a Binary File
+=== Processed Data ===
+  * Data Location:
+  * Data Format: <file>.out
+  * Link to .out listing and info: [[atmos:citation:instruments:aimms:ekfoutput|Output Files]]
+==== Processing ====
+=== DOS ===
+  * Executables used in DOS:
+      * asmbl.exe - combines the smaller files into one large file
+      * canextr.exe - check raw data files for errors
+      * ekf500_1hz_ssII_fwing.exe - creates output files
+  * To Process data using above:
+        - Open aimms folder on desktop
+        - Change into the following directory: aimms/und/AIMMS_Data \\ __Note__: cd is change directory just like your linux commands, however, to ls in DOS the command is dir
+        - Change into desired data directory, if desired data is not there see the Moving Data for Processing section below.
+        - Check that the [[atmos:citation:instruments:aimms:King_Air.DAT|King_Air.DAT]] file is in this directory, if not follow the steps in the Moving Data for Processing section below.
+        - Run asmbl.exe by enter the following in DOS command line: \\ asmbl ASCII_or_RAW_DATA_FILE_PREFIX Integer
+            * Note Integer is dependent on data type: \\ 0 for ASCII files \\ 1 for RAW files
+        - Run canextr.exe by entering following in DOS command line to check for errors: canextr RAW_DATA_FILE
+        - Run ekf500_1hz_ssII_fwing.ext entering the following in DOS command line: ekf500_1hz_ssII_fwing [[atmos:citation:instruments:aimms:King_Air.DAT|King_Air.DAT]] RAW_Data_File
+        - Copy output files (<file>.out) to proper directory on the nas drive.
+          * Directory Path Format: \\ /nas/ral/SaudiArabia/Spring09/Aircraft/KingAir_N825ST/FlightData/<FlightDate>/AIMMSData/<Base# of raw data>/
+=== Linux ===
+  * Convert AIMMS to NASA data format:
+    - Type following into command line:\\ convert_aimmstonasa file=inputfile \\ Example: convert_aimmstonasa file=03281146.aim
+    - Creates [[atmos:citation:instruments:aimms:serialaimms|<Base#>.serial.aimms.raw]]
+    - Move [[atmos:citation:instruments:aimms:serialaimms|<Base#>.serial.aimms.raw]] in the AIMMSPost Directory
+      * Directory Path Format: \\ /nas/ral/SaudiArabia/Spring09/Aircraft/KingAir_N825ST/FlightData/<FlightDate>/AIMMSPost/
+==== Moving Data for Processing ====
+        - Open WinSCP on the Desktop
+        - Enter in your Host Name, Username, and Password
+        - Click Login
+        - Your files on the write and the computers is on the left.
+        - Copy files as needed.
