DESCRIPTION OF GPS - RADIOSONDE SYSTEM:
Microcom m’s GPS based Radiosonde System MD-1610-GRS is designed to provide upper atmospheric sounding data including wind speed and direction in compliance with World Meteorological Organisation standards. It is a complete, fully automatic, all weather, upper - air sounding station that transmits, receives, logs, stores and processes Radiosonde data in real - time and produces various meteorological messages, and high resolution graphic displays.
The MD-1610-GRS system comprises of GPS based digital Radiosonde used during each flight, which transmits data in the UHF band of 400-410 MHz at low power. The data is received by a purpose built 400-410 MHz digital synthesized Receiver, with a removable Memory Module built-in. The data is logged into the Memory Module as well as being transmitted to the IBM compatible PC through a standard serial port. The Receive Computer uses dedicated software MD-1610-GRS-V4.1 for storing and processing the data.
GPS Based Radiosonde:
MicroMet GPS based Radiosondes is perhaps one of the most advanced Sonde available anywhere. It uses highly accurate, fast response sensors for recording Air Pressure, Air Temperature and Relative Humidity. The
Radiosondes has 8 sensor input channels besides logging GPS data on a SPI port. Optional sensors like Ozone, Solar Radiation can also be used for user-specific applications. The
Radiosondes uses an FPGA for signal processing and is based on an ATMEL AVR mega processor.
The Radiosondes uses the following Sensors
a) Pressure = based on Silicon-resistive bridge
b) Temperature = based on PT1000
c) Humidity = based on capacitive sensor
Weather Balloons:
MicroMet Radiosonde System uses Meteorological Balloons made of natural rubber. These balloons are produced by rotational moulding to have uniform wall thickness which prevents premature blowouts. The balloons are ozone resistant and have a reinforced neck for use in strong winds without any fear of tearing. Each balloon is inflated, inspected and tested before being dusted and sealed in moisture-proof polyethylene bag. They may be stored for up to 7 years if kept in a cool dark room. No pre-flight conditioning is required. Software :
When used with an IBM-PC compatible computer, special software MD-1610-GRS-V4.1 is provided for data storage and analysis. It provides the user with an efficient and user friendly GUI, which allows the functions of the system to be used effectively and easily. Custom software can also be written by MicroMet to suit the specific user requirements.
