How are remote agents used?
Remote Agent will be tested twice during DS1's mission. The two tests together are called the Remote Agent Experiment (RAX). During RAX Remote Agent will command working parts of the spacecraft. In order to do this, Remote Agent will need to pay attention to the current spacecraft state to execute the plans. There will also be a failure test, where Remote Agent has to diagnose failures in the spacecraft's subsystems and create new, effective plans if the failure affects the current plans.
Phase One of the RAX will last for 12 hours. Smart Executive (EXEC) of Remote Agent will have to execute a plan uplinked from the ground. EXEC must break the plan into all the necessary commands to carry out that task, such as starting and stopping thrust segments. Ground controllers will also send up a false signal that a power bus is off. Remote Agent will need to use information from other sensors to see that devices connected to the bus are still operating normally and that the sensor, not the power bus, is failing. Based on this information, EXEC will continue to follow the original plans.
Phase Two will last for six days. During this phase, DS1 will be given goals. Remote Agent has to create plans to reach the goals and execute them. Planner/Scheduler (PS) will create two separate three-day plans. The mission goals during this time include taking photographs during a certain time to be used for AutoNav and thrusting to stay on the right course. This is one step more advanced than phase one because the plan has to be made on DS1 instead of coming from the ground. Like phase one, phase two will include a simulation of failures on board that Remote Agent will have to handle. DS1 will get messages that the camera power is stuck on, a communication device has failed, and a thruster is stuck closed.

Wakala wa mbali hutumiwaje? Remote Agent itajaribiwa mara mbili wakati wa utume wa DS1. Majaribio hayo mawili pamoja yanaitwa Remote Agent Experiment (RAX). Wakati RAX Remote Agent itaamuru sehemu za kazi ya chombo cha angani. Ili kufanya hivyo, Remote Agent itahitaji kuzingatia hali ya sasa ya chombo cha angani kutekeleza mipango. Mtihani wa kushindwa: Remote Agent lazima kugundua kushindwa katika mifumo ya chini ya chombo cha anga na kuunda mipango mpya ya ufanisi ikiwa kushindwa kunaathiri mipango ya sasa. Kipindi cha kwanza cha RAX kitadumu kwa masaa 12. Mtendaji Smart (EXEC) wa wakala wa mbali itakuwa na kutekeleza mpango uplinked kutoka ardhi. Mfumo wa Exec lazima uvunje mpango katika amri zote muhimu za kutekeleza kazi hiyo, kama vile kuanza na kuacha sehemu za msukumo. Wasimamizi wa ardhi pia watatuma ishara bandia kwamba basi la umeme limefungwa. Remote Agent itahitaji kutumia habari kutoka sensorer nyingine kuona kwamba vifaa kushikamana na basi bado kazi kawaida na kwamba sensor, si bus nguvu, ni kushindwa. Kwa kuzingatia taarifa hii, Exec itaendelea kufuata mipango ya awali. Awamu ya pili itaendelea kwa siku sita. Katika hatua hii, DS1 atapewa malengo. Remote Agent ina kujenga mipango ya kufikia malengo na kutekeleza yao. Mpangaji (PS) na Mpangaji (PS) watafanya mipango miwili tofauti ya siku tatu. Lengo la mradi huo ni kuchukua picha za wakati fulani ili zitumiwe kwa ajili ya AutoNav na kusukuma ili kubaki kwenye njia sahihi. Hii ni hatua moja zaidi ya hatua ya kwanza kwa sababu mpango lazima ufanywe kwenye DS1 badala ya kuja kutoka ardhini. Kama awamu ya kwanza, awamu ya pili itajumuisha uigizaji wa kushindwa kwenye bodi ambayo Wakala wa Mbali atahitaji kushughulikia. DS1 itapokea ujumbe kwamba nguvu ya kamera imeshikamana, kifaa cha mawasiliano kimeshindwa, na thruster imeshikamana imefungwa. Ni lini Remote Agent ni juu? Wakala wa mbali hufanya kazije? Ni nini wakala wa mbali? Uplink na downlink ni nini? Ni nini AutoNav? Mfumo wa umeme wa DS1 unafanya kazije? Ni nini tofauti kati ya DS1 na NASA's Autonomous Spacecraft (NAS)? DS1 inawezaje kupiga picha? Ni teknolojia gani mpya zinazotumiwa katika DS1? DS-1 itafanya nini katika utume wake? NASA inaendelea na kazi ya DS-1 Tutajuaje ikiwa teknolojia mpya zinafanya kazi?
