“…The position of the objects of observation is determined by the specified grid sizes and limited by the specified contour. The input parameters of the algorithm are divided into 3 groups: own parameters of the calculation, parameters of the technical characteristics of the remote sensing spacecraft and radio line, parameters of the data reception point and parameters of the simulation model [26][27][28][29][30][31][32][33].…”

Remote sensing of the Earth is mainly carried out in the visible region of the spectrum, which corresponds to the current level of development of high-precision onboard instruments for Earth remote sensing. At the same time, methods and equipment for sensing in the radio- and infrared ranges of the electromagnetic spectrum are widely used and developed at a faster pace. The frequency of data acquisition ranges from once per month to once per minute, the spatial resolution ranges from kilometer to centimeter scales, and the electromagnetic spectrum covers wavebands ranging from visible light to microwave wavelengths. The efficiency of Earth remote sensing information delivery to consumers is considered under different variants of satellite-repeater network construction, taking into account the characteristics of existing and prospective high-speed radio lines of spacecrafts.

“…This suggests that the receiver firmware has been appropriately and significantly modified. In the simulated system [7], the authors suggested the creation of separate frames for sending coordinates of both satellites and pseudolites. Older solutions described in the literature assume storing pseudolites positions in databases inside the mobile receiver or transmitting stored pseudolite positions via wireless networks [8,9].…”

In the presented study, the authors deal with the problem of transmission of pseudolite coordinates to the receiver. Nowadays, there is no uniquely specified method that would provide data about the position of the pseudolite to the GNSS receiver. There is also no technical standard that defines the explicit way of performing such transmission. Solutions presented in the literature are usually tailored to the described system, which is then suited to the specific situation. The article shows that the universal methods, involving the modification of transmitted broadcast ephemeris data, cannot be universally used. The modifications could not have been introduced due to the low resolution of the quantities that are transmitted in the ephemeris data, in relation to the values that would have to be sent by the pseudolite. To overcome the implementation problems, the authors propose two solutions. The first solution presented is the modification of the RTCM SSR frame. This approach allows replacing one of the existing satellites in space with the pseudolite, while the second method involves the use of new RTCM frame for sending the pseudolite position. Finally, a numerical example of the proposed solutions is presented. At the end of the manuscript, their advantages and implementation possibilities are discussed.
