The precision of satellite positioning system depends largely on the numbers and geometric layout of the positioning satellite, the GDOP is one of the important parameters to measure the geometric layout of positioning satellites. From the perspective of GDOP, the relation between a different pseudo-satellite location and layout for the accuracy of the positioning system has been studied. For the positioning of the four pseudo-satellites, the simulation analysis of the relationship of the GDOP parameter changes with the pseudo-satellite longitude, latitude and location of the user. Studies have shown that different latitudes, the symmetrical distribution of the pseudo-satellite layout has good geometric accuracy; the same layout, the low-latitude, GDOP is less than the high-latitude; when the user moves in the regional variation in the geometric center of the pseudo-satellite layout, the GDOP values did not change and less than the value of the central region; at the same time, increasing the number of pseudo-satellite can reduce the GDOP value.

“…Combustion catalysts, as one of the main ingredients, play an essential role in the modification of the burning rate and combustion stability of solid propellants [1][2][3]. A variety of combustion catalysts, such as transition metal oxides (e.g., CuO, PbO, NiO) [4][5][6][7][8], compounds (e.g., lead salicylate, copper adipate, copper salicylate) [9][10][11], and nano-metal particles (e.g., Ni, Bi) [12][13][14], have been up to now studied extensively.…”

The fiber-like bis-(dimethylglyoximato) nickel(II) complex, Ni(DMG)2 was successfully synthesized. The obtained samples were characterized by SEM-EDS, FT-IR, XRD, and XPS. The TG-DSC-FTIR-MS coupling technique was used to characterize the thermal decomposition behavior and evolved gas analysis of Ni(DMG)2. The non-isothermal decomposition reaction kinetic parameters were obtained by both combined kinetic analysis and isoconversional Vyazovkin methods. It was found that Ni(DMG)2 begins to decompose at around 280 °C, and a sharp exothermic peak is observed in the DSC curve at about 308.2 °C at a heating rate of 10 °C·min−1. The main gaseous products are H2O, NH3, N2O, CO, and HCN, and the content of H2O is significantly higher than that of the others. The activation energy obtained by the combined kinetic analysis method is 170.61 ± 0.65 kJ·mol−1. The decomposition process can be described by the random nucleation and growth of the nuclei model. However, it was challenging to attempt to evaluate the reaction mechanism precisely by one ideal kinetic model.

Lithium Nitropyrazolates as Potential Red Pyrotechnic Colorants

Dedicated to Professor Dr. Wolfgang Beck on the occasion of his 90 th Birthday.Strontium-based red pyrotechnic colorants have fallen into disrepute due to the harmful influence of this alkaline earth metal on adolescents. In this context, the energetic character, safety, and combustion to benign nitrogen gas of nitropyrazoles are used for the design of the corresponding lithiated materials, which are investigated as potential replacements in the current work. For this purpose, the lithium salts of 3,4-dinitro-1Hpyrazole, 3,5-dinitro-1H-pyrazole, 4-amino-3,5-dinitro-1H-pyrazole, 3,4,5-trinitro-1H-pyrazole, and 4-hydroxy-3,5-dinitro-1H-pyrazole were extensively characterized by standard analytical methods, low-temperature single-crystal X-ray diffraction, studies of the thermo-chemical behavior, and sensitivity assessments. Our assumption that the high nitrogen contents and the low oxygen balances of these compounds would adjust a cool, reductive flame atmosphere essential for red emissions by lithium was put to the test.
