摘要

The Columbia Scientific Balloon Facility (CSBF) in Palestine, Texas launches high-altitude scientific payloads on balloon vehicles. These balloons can be as large as 60 million cubic feet, reach a float altitude of 160,000 feet, carry a payload of up to 8,000 pounds, and stay at float for over a month. The CSBF also provides telemetry for the science payload by integrating one of two types of support packages. The type of support package integrated depends on whether the flight will stay in range of line of sight (LOS) or will exceed LOS requiring the use of over the horizon (OTH) telemetry. The weights of these systems range from 100 pounds to 350 pounds depending upon the use of redundant systems, equipment for high data rates, and batteries and/or solar panels for power requirements. These weight values are not as significant for larger payloads but can be crippling for smaller payloads. In addition, these support package systems are fairly expensive, placing a high importance on recovery. A lightweight and inexpensive telemetry system could be beneficial for various reasons. First, it would allow scientists to fly lightweight payloads on large balloons reaching even higher altitudes. Second, scientists could fly lightweight payloads on less expensive balloons such as meteorological balloons. Depending on the payload, these flights could be fairly inexpensive and even disposable. Third, a compact telemetry system on any balloon will free up more room for the science portion of the payload. In response, a compact telemetry system called the Micro-Instrumentation Package (MIP), is currently being developed. The MIP will provide uplink and downlink communications, an interface to the science, housekeeping information including global positioning system (GPS) position, and relays. Instead of a power-hungry microprocessor, the MIP's central unit will be composed of a microcontroller. Microcontrollers are lower power, easily programmed, and can be purchased for less than ten dollars. For uplink and downlink telemetry, the MIP will use an LOS serial transceiver and an IRIDIUM unit for OTH flights. A relay deck will also be included for powering subsystems and for flight termination. Furthermore, the science will be able to interface to the MIP through a serial connection, although the data rates for the science interface will be limited compared to those of standard telemetry support packages. Overall, the MIP will provide the basic necessities for the safe operation of a balloon flight without the weight and the expense of the current CSBF telemetry support packages. This paper will explain more about CSBF operations and delve further into the MIP development and capabilities
