Accelerometers are used to perform initial levelling and correct the gyro drift on the move. Typically, accelerometer with a range of ±10g with overall bias stability better than 2 mg and scale factor composite repeatability of better than 1000 ppm is required for the AHRS application. Current solutions in the market are mainly based on either vibrating quartz structures or traditional precision mechanics. These solutions suffer from high cost and fragility. MEMS is an inherently rugged technology and has great potential to bring forth novel solutions on the harsh environment and safety critical applications and enable new solutions due to its size, ruggedness and potential cost benefits. We report a new technological platform termed IRIS™ and a new accelerometer product based on that is called RS9000 family. RS9000 is interfaced with an open-loop electronic circuit and is comprised of a novel MEMS element designed specifically for high bias stability. RS9010 is a ±10g accelerometer with in run bias stability of better than 120µg, long term composite bias repeatability of better than 1.5mg, scale factor repeatability of 400ppm and vibration rectification of better than 65µg/g2. To our knowledge, this is the highest accuracy reported for a MEMS sensor operating in open-loop.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].

CBOC consists of a superposition of two sine Binary Offset Carrier (BOC) waveforms: a sine BOC(1,1) and a sine BOC(6,1) component. CBOC modulation has higher spectral components than BPSK modulation currently used in GPS, and therefore would require a wider bandwidth than what is currently used in mass-market GPS receivers in order to achieve the full performance. Fortunately, CBOC signals can be processed with a sine BOC(1,1) receiver, with lower bandwidth and sampling frequency needs. This paper analyzes how much deterioration (if any) in terms of tracking accuracy (i.e., code tracking error variance and robustness to multipath) occurs when we process a CBOC signal with a reference sine BOC(1,1) receiver (instead of processing it with a CBOC receiver). The analysis focuses especially on narrowband receiver cases (i.e., front-end double-sided bandwidth lower or equal to 5 MHz), which are the cases of interest in mass-market applications. Analytical closed-form expressions of signal Power Spectral Densities (PSD) are derived by taking into account the rate differences of the two components of CBOC signal, and tracking results are analyzed in terms of tracking error variances and multipath error envelopes.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].

Effects such as multipath fading, shadowing, jamming of the waveform not only greatly limit the navigation accuracy, but also increase the outage probability that occurs when the received signal level falls below the minimum threshold. Newer navigation approaches have focused on employing terrestrial signals that maintain higher signal power such as digital television (DTV), cellular, etc. These are referred to as signals of opportunity (SoOP). The focus of this research is using these signals in a time difference of arrival (TDOA) cooperative navigation network. A major problem arises with relation to convergence of the positioning algorithm for this type of network. To address this problem, our research studies this problem from a different perspective. Here we will pose the problem as a convex optimization problem and address it as such. The main idea being that if the problem is structured in this form, we can use this well understood area to develop algorithms for faster convergence with respect to cooperative navigation. As such, this research is a combination of analytical analysis, algorithm development, and simulation results that describe performance under certain conditions.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].

The system is equipped with webcams, an MEMS IMU and up to four GNSS receivers. During this development, several (non negligible) problems have been solved in order to obtain good quality after the data processing. One of the main problems of the low cost systems concerns the occurrence of GNSS outages. In this case, the IMU can only estimate the trajectory and the attitude of the vehicle for short periods. For this reason, considering the high number of frames available (about 3–5 frame per second, fps), a vision-based navigation (VBN) approach, called GIMPhI (GNSS IMU and PHotogrammetry Integration), has been adopted and tested. The navigation solutions have been refined by means of integration with a photogrammetric approach (bundle block adjustment) and a rigorous weight matrix has been adopted in order to consider the different accuracies of the various sensor observations (GNSS, IMU and images). A detailed description of this integrated approach is presented in this paper. The first tests and the achieved results are then shown in order to evaluate the reliability of the proposed approach.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].
