“…Lastly, the electronically scanned feed combines the best features of the previous two methods to generate tracking errors (RCC, 2008). It has been found that electronically scanned feed subsystems have a superior auto-tracking performance overall (Goswami, Sucharita, & Arya, 2003). For the purposes of this paper, we will focus on the electronically scanned feed assembly because the TTS antennas being analyzed for this paper utilize this type of feed assembly system.…”

AGENCY USE ONLY (Leave blank)2. REPORT DATE September 2013 In the world of missile testing, telemetry plays a vital role in the evaluation of these weapon systems. Telemetry is defined as the process of taking measurements from a distance, or remote location. As measurements are made within the missile, the data is packetized and transmitted down to ground stations in real time. Once the data is accumulated, analysts review the data and evaluate the results of the missile test. REPORT TYPE AND DATES COVEREDLaunching a missile is a major test event that requires significant coordination and a considerable amount of funding. Collecting as much data as possible is crucial and always a fundamental requirement. Therefore, the telemetry tracking ground stations receiving the data play just as an important role as the missile itself. The ground stations must be reliable systems, where periodic maintenance and technical refreshing are key elements in the risk management of the receiving system. This paper explores the effectiveness of predicting system failures by carefully analyzing antenna data metrics already made available to system users. By establishing a standard for evaluating these tracking systems, variances in the performance metrics over time may predict future system failures. By addressing potential issues preemptively, lastminute critical failures can be significantly reduced while making the system's availability and reliability much higher.

“…The location of ground receiving station in space diversity is estimated using predicted trajectory and G/T of respective ground receiving station. These ground stations are connected in network and operated in different modes such as Mono-pulse Mode (amplitude comparison mode), E-Scan Mode 6 and Internal Designated Mode (IDM-Simulated and predicted information) to track the vehicle.…”

A Novel Loss Tolerant Data Transmission Schemes for Airborne Telemetry System of a Long Range Aerospace Vehicle

2022

The on-board telemetry system of an aerospace vehicle sends the vehicle performance parameters to the ground receiving station at all instances of its trajectory. During the course of its trajectory, the communication channel of a long range vehicle, experiences various phenomena such as plume attenuation, stage separation, manoeuvring of a vehicle and RF blackout, causing loss of valuable telemetry data. The loss of communication link is inevitable due to these harsh conditions even when using the space diversity of ground receiving systems. Conventional telemetry systems do not provide redundant data for long range aerospace vehicles. This research work proposes an innovative delay data transmission, frame switchover and multiple frames data transmission schemes to improve the availability of telemetry data at ground receiving stations. The proposed innovative schemes are modelled using VHDL and extensive simulations have been performed to validate the results. The functionally simulated net list has been synthesised with 130 nm ACTEL flash based FPGA and verified on telemetry hardware.

“…In test ranges throughout the world, multiple auto-tracking sensors like electro-optical tracking stations (EOTS) and tracking radars are deployed at various geographical locations for generation of the trajectory of the missile under test (MUT). Also, these facilities provide tracking aid to radio-frequency telemetry stations with the help of which, the telemetry systems acquire the MUT for monitoring the telemetry health parameters including inertial navigation system (INS) data 1,2 . Thus, accurate testing of the missiles depends directly on the calibration of these tracking sensors so that the trajectories of the MUT generated by various tracking sensors do not provide erroneous or misleading results.…”

Potential of Multi constellation Global Navigation Satellite System in Indian Missile Test Range Applications

et al. 2020

View full text Add to dashboard Cite

In this paper, the potentials of using Global Navigation Satellite System (GNSS) techniques in the complex calibration procedure of the tracking sensors for missile test range applications have been presented. The frequently used tracking sensors in test range applications are- electro-optical tracking stations (EOTS) and tracking radars. Over the years, the EOTS are used as the reference for bias estimation of the radars. With the introduction of GPS in test range applications, especially the DGPS, the reference for bias estimation got shifted to DGPS from the EOTS. However, the achievable position solution accuracy is limited to the order of a few meters for DGPS, EOTS, and Radars. With the evolution of Multi-constellation GNSS and carrier-phase based measurement techniques in satellite navigation, achievable position solution accuracies may be improved to sub-meter level. New navigation techniques like real time kinematic (RTK) and precise point positioning have the potentials for use in the calibration procedures of the missile test ranges to the accuracies of centimeter-level. Moreover, because of the availability of a large number of navigation signals over the Indian region, multi-constellation GNSS receivers can enhance signal availability, reliability, and accuracies during the calibration of missile test ranges. Currently available compact, low-cost GNSS modules also offer the possibilities of using these for cost-effective, networked RTK for dynamic calibration of test ranges reducing cost and resource requirements.
