“…Right now, more than 25,000 satellites are rounding our earth which has been launched by different country or organization [3], [4]. Global positioning systems (GPS) is one of the important application fields of these satellites [5], [6]. Nowadays, GPS plays an important role in military, civil, and commercial applications in ways that make their work more productive, safer, and easier [6], [7].…”

In this paper, a compact two-shape slot microstrip antenna is proposed for global positioning system (GPS) satellite application. The proposed antenna is designed with FR 4 substrate with a height of 1.6 mm, a dielectric constant εr of 4.3 within a compact size 56 x 56 mm2 area. The design parameters are optimized to achieve good performance. At the optimum setting of design parameters, this antenna shows good characteristics to cover L1 band 1,575.42 MHz, ± 12 MHz frequency which is used for GPS satellites. At the 1,572 MHz resonance frequency, this antenna achieves a minimum return loss of -30 dB covering a frequency bandwidth of 50 MHz (1,550 MHz – 1,600 MHz) at -10 dB reference level which ensures 100% bandwidth coverage of the L1 band. Besides, the proposed antenna achieved a maximum gain of 8.3 dBi and a beam width of 1010 at -3 dB point. In terms of other performance, such as voltage standing wave ratio (VSWR), directivity, radiation pattern, the proposed antenna shows good performance for the application of GPS satellites.

“…Актуальность исследования процессов радиационной электризации диэлектриков электронами средних энергий, соответствующих низкоэнергетической части электронов геомагнитной плазмы, обусловлена необходимостью предотвращения мощных электроразрядных процессов как на поверхностях, так и в силовой кабельной сети космических аппаратов (КА) [1]. Верхняя граница спектра ЭМ-помех, обусловленных электроразрядными процессами при радиационной электризации солнечных батарей электронами геомагнитной плазмы в режиме нормального градиента потенциала, достигает нескольких GHz [2][3][4][5][6][7], что указывает на то, что время нарастания разрядного тока может иметь величину порядка 1 ns. При этом среднее значение разрядного тока, протекающего через защитные стекла фотопреобразователей солнечных батарей и тыльный электрод, достигает 25 A, а амплитудное значение разрядного тока может достигать 100 A [1].…”

The physico-mathematical model applied to ground tests for geomagnetic plasma exposure based on the combined consideration of surface and bulk processes of transport and charge accumulation for calculating the kinetics of charging high-resistance dielectrics irradiated by medium-energy monoenergetic electrons (from 6 to 30 keV) is proposed. The model takes into account the contribution to the charging of the dielectric by the trains of longitudinal optical phonons generated by each thermalizing primary electron with energy below the band gap of the dielectric, which supplements the induced conduction current due to the generation of electron-hole pairs. As a result, the current induced by trains of longitudinal optical phonons of the tunnel conductivity through free electron traps is introdused, as well as the current induced in the conduction band due to multiphonon ionization the electron traps by trains of longutudinal optical phonons in the region of existence of electric field. Using the example of the α-Al2O3 (sapphire) dielectric, the results of computer simulation of the internal currents distributions, charges, and electric field in the dielectric with the open surface irradiated by monoenergetic electrons with energies from 6 to 30 keV are presented according with the achievement the quasi-equilibrium in the irradiated part of the dielectric and with switching of the energy of primary electrons during the irradiation process.
