摘要： The present invention relates to satellite systems and more particularly, to the provision of a satellite system and method which provides a smooth transition for legacy systems to exploit higher communication frequencies. The improved system and methods described herein are novel in that they separate the standard gateway frequency bands from the user frequency bands, and they incorporate a switch that provides the capability to switch between two frequency bands on the gateway side, while keeping the same uplink and downlink frequencies of operation for the user side. This ability for in-orbit switching of the gateway frequencies of operation offers major benefits in terms of a boost in throughput capacity and flexibility in satellite replacement transition logistics, while maintaining system performance.

摘要： The present invention relates to satellite systems and more particularly, to the provision of novel systems and methods for verifying the in-orbit performance and operation of satellite communications subsystems. In contrast to traditional Payload IOT (in-orbit test), the invention operates without an uplink signal, by generating hardware-specific signatures using isolated, internally generated, thermal noise. It has been found that this noise provides a very stable, repeatable signal for testing. Prior to launch, a repeater command sequence is executed to generate a hardware-specific signature based on the internally-generated noise. The same repealer command sequence is then executed in-orbit to determine whether the hardware-specific signature has changed. The two signatures may be recorded and compared using a simple tool such as a spectrum analyzer. The methods also include novel use of the sun as a test signal source to calibrate equipment, to quantify atmospheric effects and to be used as an intermediate reference power level during measurements.
摘要翻译：本发明涉及卫星系统，尤其涉及提供用于验证卫星通信子系统在轨性能和操作的新颖系统和方法。与传统的有效负载IOT（在轨测试）相比，本发明在没有上行链路信号的情况下通过使用隔离的内部产生的热噪声产生特定于硬件的签名来工作。已经发现，这种噪声为测试提供了非常稳定，可重复的信号。在启动之前，执行中继器命令序列以基于内部产生的噪声生成硬件特定的签名。然后在轨执行相同的排斥器命令序列以确定硬件特定的签名是否已经改变。这两个签名可能会被记录下来，并使用频谱分析仪等简单工具进行比较。这些方法还包括将太阳作为测试信号源的新型用途，以校准设备，量化大气效应并在测量过程中用作中间参考功率电平。

摘要： Systems, methods and techniques are presented for discovering optimal solutions to satisfy communication traffic demands to a NGSO and GSO satellite constellations used for telecommunication. When multiple ground demands (mobile and stationary) are present, a satellite constellation requires an assignment of satellite resources to optimally match the ground demands. The systems, methods and techniques presented can utilize an optimization structure to maximize the objective function, using linear programming in combination with simulation and predictive features. The techniques presented determine optimal or quasi-optimal allocation of scarce and highly constrained satellite resources in an efficient manner. These techniques take into account maximizing capacity while protecting other geostationary and non-geostationary networks.

摘要： The present invention relates to satellite systems and more particularly, to the provision of a satellite system and method for communications applications, with global coverage. An optimal method of providing global broadband connectivity has been discovered which uses two different LEO constellations with inter-satellite links among the satellites in each constellation, and inter- satellite links between the constellations. The first constellation is deployed in a polar LEO orbit with a preferred inclination of 99.5 degrees and a preferred altitude of 1000 km. The second constellation is deployed in an inclined LEO orbit with a preferred inclination of 37.4 degrees and a preferred altitude of 1250 km.

摘要： The present invention relates to satellite systems and more particularly, to the provision of a novel, non-geostationary satellite system and method for weather and climate monitoring, communications applications, scientific research and similar tasks, with global coverage. Contrary to the teachings in the art it has been discovered that global coverage may be obtained using a constellation of six satellites in two orthogonal, 24 sidereal hour orbits (geosynchronous) with inclinations of 70° to 90°, and eccentricities of 0.275 - 0.45. By placing three of the satellites in a first orbit with an apogee over the north pole, and three of the satellites in a second, orthogonal orbit with an apogee over the south pole, global coverage may be obtained. As well, the satellites in these orbits avoid most of the Van Allen Belts.

摘要： The present invention relates to satellite systems and more particularly, to the provision of a satellite system for weather and climate monitoring, communications applications, and scientific research at higher latitudes, referred to as the circumpolar region and defined here as the area with latitudes greater than 60°, in either the northern hemisphere or the southern hemisphere. Contrary to the teachings in the art it has been discovered that a satellite system and method may be provided using satellites in 24 sidereal hour orbits (geosynchronous) with inclinations (70° to 90°), orbital planes, right ascensions and eccentricities (0.275 - 0.45) chosen to optimize coverage of a particular service area located at high latitudes. A constellation of two satellites can provide continuous coverage of the circumpolar region. The satellites in this orbit avoid most of the Van Allen Belts.
