Contemporary auto navigation systems are truly excellent. Have you ever considered acquiring one? People who do not have or have never had a modern auto navigation system, or GPS (Global Positioning System) as it is also known as. will almost certainly not realize quite how much knowledge they provide. It is no longer just an item to stop you from getting lost while you are travelling from A to B.
Far from it. Modern GPS systems will tell you whether you are passing monuments, sites of historical importance or beauty, churches, hotels, restaurants, taverns, garages, petrol stations, airports and practically anything else that you would like it to inform you about. They have moved on from being only an on screen map to being a travel guide and much more..
If you are thinking about acquiring a GPS auto navigation system, it is worth learning a bit about how they work, so that you can better understand what they do, what they are capable of doing and how they do it. This is practical knowledge for when it comes to deciding which system to decide on, because not all GPS systems are the same and some offer more functions than others.
All car GPS navigation devices use satellites to help them determine their location. (This is not always the case with ships, because some water ways use land-based tracking stations.
The GPS is like a radio receiver, so it picks up signals from overhead satellites and interprets that data in order to determine where it is. In order to do this job properly, it needs the signals from three satellites.
This is known as triangulation and is very accurate, frequently to within a metre or a yard. However, in order to make sure of even more accuracy, the data from a fourth satellite is used as a check. There is very little margin for error when four satellites are being used for pin-pointing a position.
A GPS device will tell you which way to go and if you go off route, it will advise you the best manner for getting back to the right road. However it will also do more than that. Before you begin out on your journey from A to B, you have to type in those two locations.
The GPS will then enquire of you whether you would like to go by the quickest route, the most scenic route or whether you would like to avoid motorways altogether.
This is a great role, but it can do more than that too. If you sort in the name of a restaurant along the way or a monument you would like to see, it will steer you from A to B via your place of interest.
One last item, be certain that the system that you purchase is upgradeable. Some are upgraded automatically, but you have to pay a monthly or annual fee. Others will sell you an upgrade which you have to install yourself. If you are at ease with making your own upgrades, all well and good, but just be aware that systematically upgrading the software is vital.

The Ancient Chinese Lunar Calendar
Prior to their adoption of the Western solar calendar scheme, the Chinese almost wholly followed their own lunar calendar for determining the times of planting and harvesting and festival days. Although people in China today use the Western calendar for almost all business, governmental and practical matters of daily life, the old method still serves as the basis for determining many seasonal holidays. This coexistence of two calendar schemes has long been accepted by the people of China.
However, this does not only happen in China, it also occurs in most other Eastern countries, like Thailand, and most Arabic countries.
A lunar month is determined by measuring the period of time needed for the moon to finish its full cycle of 29 and a half days, a standard that makes the lunar year a full eleven days shorter than its solar counterpart. This difference is made up every 19 years by the addition of seven lunar months.
The 12 lunar months are further divided into 24 solar divisions characterized by the four seasons and times of heat and cold, all of which bear a close relationship to the annual cycle of agricultural work.
The Chinese calendar – very much like the Hebrew calendar- is a combination of the solar and lunar calendars in that it attempts to have its years coincide with the tropical year and its months coincide with the synodic months. It is not surprising that a few similarities exist between the Chinese and the Hebrew calendar.
For instance, an ordinary year has 12 months, a leap year has 13 months. An ordinary year has 353, 354, or 355 days, a leap year has 383, 384, or 385 days. When determining what a Chinese year will be like, one needs to make a couple of astronomical calculations.
First of all, you have to work out the dates for the new moons. In these instances, a new Moon is the completely black Moon (that is to say, when the Moon is in conjunction with the Sun), not the first visible crescent, as is used by the Islamic and Hebrew calendars. The date of a new moon is then the first day of a new month.
The reason why the majority of countries which had their own calendars had to dump them in favour of the Western, Julian calendar that we use today, is business. First the British and then the Americans ran international business and they used the Gregorian calendar. Anyone who wanted to work with them had to follow suit. This is why national policy often varies from local custom in Third World countries.
The government desires to trade on the International markets, but the ordinary family in the country can not. So, the government adopted the Gregorian calendar but the people only pay lip service to it. I live in Thailand and people here do not even use the 24 hour day divided into two halves. Their day has four sections of six hours each and the first part starts at 6AM, not midnight. Therefore, they have four 4 o’clocks a day, for example but no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for instance in Muslim countries.
