—This paper summarizes what is needed to achieve a real-time-157 dBm GPS C/A signal acquisition sensitivity in ASIC and software receiver implementations for a cold and a warm start. Two receivers (one ASIC receiver working in the time domain and one PC software receiver working in the frequency domain) are implemented in a highly efficient way. The(More)
—This paper introduces a combined GNSS/UMTS receiver architecture. After a review of the state-of-the-art, a configurable GNSS/UMTS architecture is proposed. The investigated concept is based on a reconfigurable receive chain to prevent duplication of hardware, which will result in considerably lower costs. The biggest challenge in the design of Gali-leo(More)
Under the pressure of cost reduction and productivity improvement, this paper presents a new methodology which provides a fast inspection of defective objects and generates a real time motion trajectory for processing objects being conveyed with high speed in an industrial large-scale production. The image data obtained by a multispectral imaging system is(More)
This paper contains selected test results of an indoor positioning prototype system making use of GPS/Galileo signals on L1/E1 and L5/E5a in addition to WiFi data, ZigBee data and a MEMS-based dead reckoning algorithm called pedestrian navigation system (PNS). The system uses a partially coherent ultra-tightly coupled integration scheme. The GNSS signal(More)
Determination of communication satellite orbital parameters via accurate measurements plays a vital role to control satellites in a sturdily way. The anomalies occurred in satellite orbit must be determined in time to keep it in its nominal orbit using on-board active control systems such as thrusters. In this study, utilization of a Ku-band navigation(More)
In the course of this paper, a by IFEN GmbH developed integrated navigation device for aiding and rescuing fire fighters in emergency situations is presented. In areas with sufficient signal strength the respective rescue force is tracked by means of GNSS/INS position information, whereas indoor or in areas without GNSS support, the positioning is conducted(More)
This paper introduces a combined UMTS/NAVSAT receiver architecture. After a review of the state-of-the-art, a configurable UMTS/NAVSAT architecture is proposed. The investigated concept is based on a reconfigurable receive chain to prevent duplication of hardware, which will result in considerably lower costs. The biggest challenge in the design of NAVSAT(More)
In this paper we calculate the storage capacity of the perceptron for block-wise semantically correlated patterns. The set of patterns is divided into blocks, each block consisting of n binary patterns. The patterns in a block have the overlap R with each other and patterns in diierent blocks have overlap 0. Using a cavity method, which was recently(More)
