Study on application and simulation of Kalman filter technology in SINS Because Kalman filter some merits, such as provided a fast and accurate method for SINS, adopting it to do initial alignment in this paper. The Kalman filter theory is introduced and the dynamic error vector equation of the initial alignment is derived at the first. Using velocity error as exterior value of observation, maneuverable characteristic that is influenced with system's observability and its degree is studied at length by do amount of simulations and experiences.

My Dog was a very pleasant and loving Companion to me, for no less than sixteen Years of my Time, and then dy'd, of meer old Age; as for my Cats, they multiply'd as I have observ'd to that Degree, that I was oblig'd to shoot several of them at first, to keep them from devouring me, and all I had; but at length, when the two old Ones I brought with me were gone, and after some time continually driving them from me, and letting them have no Provision with me, they all ran wild into the Woods, except two or three Favourites, which I kept tame; and whose Young when they had any, I always drown'd; and these were part of my Family: Besides these, I always kept two or three houshold Kids about me, who I taught to feed out of my Hand; and I had two more Parrots which talk'd pretty well, and would all call Robin Crusoe; but none like my first; nor indeed did I take the Pains with any of them that I had done with him.

至于我的那些猫，前面也已说过，由于繁殖太多，我不得不开枪打死了几只，免得它们把我的东西通通吃光。后来，我从船上带下来的两只老猫都死了，我又不断地驱逐那些小猫，不给它们吃东西，结果它们都跑到树林里去，变成了野猫。只有两三只我喜欢的小猫被我留在家里驯养起来。可是每当它们生出小猫时，我就把小猫投在水里淹死。这些都是我家庭的一部分成员。另外我身边还养了两三只小山羊，教会它们在我手里吃东西。此外，还养了两只鹦鹉，也会说话，也会叫"鲁宾逊"，可都比不上第一只说得那么好；当然，我在它们身上花的功夫也没有第一只那么多。

This single Stick, which you now behold ingloriously lying in that neglected corner, I once knew in a Flourishing State in A Forest, it was full of Sap, ful l of Leaves, and full of Boughs; but now, in vain does the busie Art of Man pret end to Vye with Nature, by tying that wither'd Bundle of Twigs to its sapless Tr unk;'tis now at best but the Reverse of what was, a Tree turn'd upside down, th e Branches on the Earth, and the Root in the Air;'tis now handled by every Dirt y Wench, condemn'd to do her Drudgery, and by a Capricious kind of Fate, destin' d to make other Things Clean, and be Nasty it self: At Length, worn to the Stumps in the Service of the Maids,'tis either thrown out of Doors, or condemn'd to its last use of kindling Fires.

请看看这根扫帚把，它现在灰溜溜地躺在偏僻的角落，而以前我曾在树林里碰见过它，那时它风华正茂，汁液充沛，枝叶繁盛。如今它完全变了样，却还有人自作聪明，想靠人类的手工同大自然竞争，拿来一束枯枝捆在它那早已干瘪的身上，结果是枉费心机，不过颠倒了它原来的位置，使它枝干朝地，根梢朝天，成为一株头朝下的树，然后落在干脏活累活的女仆们的手里使用。从此它受命运的摆布，把别人打扫干净，而自己却变得又脏又臭，在女仆们手里折腾多次之后，最后被扔出门外，或者作为引火的柴禾被投进火里。

When we had done this, we came back to our Castle, and there I fell to work for my Man Friday; and first of all, I gave him a pair of Linnen Drawers, which I had out of the poor Gunners Chest I mention'd, and which I found in the Wreck; and which with a little Alteration fitted him very well; then I made him a Jerkin of Goat's-skin, as well as my Skill would allow; and I was now grown a tollerable good Taylor; and I gave him a Cap, which I had made of a Hare-skin, very convenient, and fashionable enough; and thus he was cloath'd for the present, tollerably well; and was mighty well pleas'd to see himself almost as well cloath'd as his Master: It is true, he went awkardly in these Things at first; wearing the Drawers was very awkard to him, and the Sleeves of the Wastcoat gall'd his Shoulders, and the inside of his Arms; but a little easing them where he com plain'd they hurt him, and using himself to them, at length he took to them very well.

我让星期五把所有的骷髅、人骨和人肉以及那些野人吃剩下来的东西收集在一起，堆成一堆，然后点上火把它们通通烧成灰烬。我发现星期五对那些人肉仍垂涎欲滴，不改他吃人的天性。但我明显地表现出对吃人肉的事极端憎恶，不要说看到这种事，甚至连想都不愿想。我还设法让他明白，如果他敢再吃一口人肉，我就把他杀了，这才使他不敢有所表示。办完这件事后，我们就回到城堡里去了。一到那里，我就开始为星期五的穿着忙碌起来。首先，我给了他一条麻纱短裤。这条短裤是我从那条失事船上死去的炮手箱子里找出来的。这件事我前面已提到过了。短裤略改一下，刚刚合他的身。然后，我又用羊皮给他做了件背心。我尽我所能缝制这件背心。

About a Year and half after I had entertain'd these Notions, and by long musing, had as it were resolved them all into nothing, for want of an Occasion to put them in Execution, I was surpriz'd one Morning early, with seeing no less than five Canoes all on Shore together on my side the Island; and the People who belong'd to them all landed, and out of my sight: The Number of them broke all my Measures, for seeing so many, and knowing that they always came four or six, or sometimes more in a Boat, I could not tell what to think of it, Or how to take my Measures, to attack Twenty or Thirty Men single handed; so I lay still in my Castle, perplex'd and discomforted: However I put my self into all the same Postures for an Attack that I had formerly provided, and was just ready for Action, if any Thing had presented; having waited a good while, listening to hear if they made any Noise; at length being very impatient, I set my Guns at the Foot of my Ladder, and clamber'd up to the Top of the Hill, by my two Stages as usual; standing so however that my Head did not appear above the Hill, so that they could not perceive me by any Means; here I observ'd by the help of my Perspective Glass, that they were no less than Thirty in Number, that they had a Fire kindled, that they had had Meat dress'd.

我自从有了这些想法之后，平时就经常会想到这件事，可是因为没有机会付诸实施，因此一直都毫无结果。这样大约又过了一年半光景。一天清晨，我忽然发现有五只独木舟在岛这头靠了岸，船上的人都已上了岛，但却不知道他们去哪儿了。他们来的人这么多，把我的计划彻底打破了。因为我知道，一只独木舟一般载五、六个人，有时甚至更多。现在一下子来了这么多船，少说他有二三十人，我一个人单枪匹马，如何能对付他们呢！因此，我只好悄悄躲到城堡里去，坐立不安，一筹莫展。可是，我还是根据过去的计划，进行作战准备，以便一有机会，立即行动。我等了好久，留神听他们的动静，最后，实在耐不住了，就把枪放在梯子脚下，像平时那样，分作两步爬上小山顶。我站在那里，尽量不把头露出来，唯恐被他们看见。我拿起望远镜进行观察，发现他们不下三十人，并且已经生起了火，正在煮肉。至于他们怎样煮的，煮的又究竟是什么肉，我就不得而知了。
