The invention relates to generating regional tropospheric correction information for correcting observations useful for estimating phase ambiguities and/or a position of global or regional navigation satellite systems (NSS) receiver(s). For each of a plurality of reference stations, at least one troposphere correction parameter is estimated (s30) by evaluating NSS observation equations using i) precise satellite information or the information derived from the precise satellite information, and ii) received multiple-frequency-signals-based raw observations or a linear combination thereof. The regional tropospheric correction information is then generated (s40) based on the estimated troposphere correction parameter(s) per reference station, the tropospheric correction information comprising a regional tropospheric delay function(s) and coefficients representing a tropospheric delay affecting a NSS signal passing through the troposphere in a region of interest. The generated tropospheric correction information may then be sent (s50) to NSS receiver(s) and used by the receiver(s) for example to facilitate position determination.

The present disclosure relates to a measuring instrument and a method implemented in such a measuring instrument. The measuring instrument includes an image sensor, an actuator, a control unit and a processor. The actuator is arranged to move a field of view of the image sensor. The control unit is configured to cause the image sensor to capture at least one digital image during motion of the field of view of the image sensor by the actuator. The exposure time for capturing the digital image is longer than an identifiable section of a regulating pattern for modulation of an optical radiation either emitted or reflected by at least one target. The processor is configured to process at least a portion of the captured image for detecting in the at least one portion the identifiable section of the regulating pattern. Such a measuring instrument is advantageous for detecting and/or identifying a target in the vicinity of the instrument.

A transmit light signal is emitted toward a target at an emission time. An optical subsystem of a receiving system receives a return light signal which is converted to a return electrical signal. At least one attenuator applies an attenuation to at least one of the return light signal and the return electrical signal. The attenuation varies, as time passes, after emission of the transmit light signal, according to a time -dependent attenuation function such that the attenuation is maximum at a critical time elapsed since an emission time of the transmit light signal. The critical time is dependent on at least one geometrical parameter of the optical subsystem. A receive time is determined from the return electrical signal. The emission time and the receive time are used to calculate a measured distance.

A Global Navigation Satellite System (GNSS) chipset embedded within the cellular device is accessed. The GNSS chipset calculates raw pseudoranges. The raw pseudoranges are extracted from the GNSS chipset for processing elsewhere in the cellular device outside of the GNSS chipset. A position fix is calculated based on the raw pseudoranges. At a first point in time, a first image, and at a second point in time, a second image are obtained with an image capturing device that is in a known physical relationship with the cellular device. An estimate of a distance that the cellular device moved from the first point in time to the second point in time is calculated by processing image data collected from the first point in time to the second point in time. The position fix is processed based on the estimate of the distance.

Novel solutions, which can include devices, systems, methods, than can measure earthquakes and other displacement events. Some solutions feature the integration of real-time, high-rate global navigation satellite system (GNSS) displacement information with acceleration and/or velocity data within a single device to create very high-rate displacement records. The mating of these two instruments allows the creation of a new, very high-rate displacement measurement device that has the full-scale displacement characteristics of GNSS and high-precision dynamic motions of seismic technologies. Such a device can be used for earthquake early warning studies and other mission critical applications, such as volcano monitoring, building, bridge and dam monitoring systems.
