The translation of GNSS authentication features to secured services in consumer and professional receivers may lead to some innovations and standards in the future. Some open points and challenges in this area will also be presented. They relate to key management, combination of authenticated and non-authenticated signals and sensors, authentication in an A-GNSS context where most receivers will operate, and integration of an authentication status in the existing location services

The PU localization problem in CR networks is in general different from localization in other applications such as Wireless Sensor Networks (WSN) and Global Positioning System (GPS), due to the following two features. First, a PU does not cooperate or communicate with CRs since they are opportunistic users of the PU spectrum band. Therefore, very limited knowledge about PU signaling, such as transmit power, modulation scheme and synchronization, is available to CRs. Second, since CRs need to detect and localize PUs in the entire coverage area at a very low signal-to-noise ratio (SNR), cooperation among a large number of CRs is necessary, which introduces important accuracy and complexity constraints.
In this talk, we will explore a set of CR cooperative localization algorithms for single and multiple PUs using different antenna configurations and available measurements, and analyze their cost performance trade-offs both theoretically and experimentally.

This talk will first highlight the impact of multipath propagation on the accuracy of wireless range and position estimation. The important influence of bandwidth and the benefit of MIMO processing will be analyzed. Next it will be shown how one can make use of multipath to benefit from improved positioning accuracy, robustness, and a relaxed need for infrastructure nodes. Analytical performance bounds, their experimental validation, and algorithms derived thereof will be discussed. Finally, it will be shown that a multipath-enabled positioning system is a showcase example of a cognitive dynamic system that can optimize the information gained from each measurement, exploiting its memory of past measurements to plan future measurements. The environment map it collects can be used to predict the propagation characteristics, yielding location-awareness for positioning and communications. It is concluded that the use of position information may become as important to 5G networks as other new, disruptive technologies such as massive MIMO and mm-wave.

The talk will also give evidence that, thanks to the outstanding piece of engineering that GNSS chipsets are, RTK positioning at decimetre level is currently feasible in consumer devices. Protocols (the 3GPP LPP) and operating systems (the Android GNSS Hardware Abstraction Layer) that support the transmission of carrier phase measurements already exist. Experimental results using phones equipped with Broadcom chipsets will show that the chipsets performance is also at the required level to be suitable for RTK. The effects of the antenna, the baseline length, the use of another type of receiver as reference, etc. will be discussed in detail, as well as the need to tune cycle slip detectors given the abundance of these phase jumps produced by fading and the rough environment.
