The satellite navigation technology has been used in archaeology for nearly 20 years and has been fully utilized in archaeological investigations and excavations.
First, in archaeological investigations, archaeologists can use satellite navigation technology to assist in recording survey routes, finding and determining the location of the site, understanding altitude, and mastering spatial information such as topography and environmental features, and site boundaries. Figure 10-1 shows the site of cultural relics excavation. In the next archaeological excavation, the remains, phenomena and even each object or pottery in the site are in specific locations in the specific probe, using the accurate spatial data provided by satellite navigation technology to represent their respective locations. It is also an important material for studying ancient socio-economic, cultural and social forms.
So, using satellite navigation technology According to the spatial distribution of various relics and artifacts in the site, from the spatial location of archaeological remains or phenomena, combined with remote sensing technology and geographic information system technology to establish a database and graphic image library with multiple spatial information and attribute information coexisting, which is convenient Multiple spatial analysis and simulations were carried out to reconstruct and restore the social situation at that time in an intuitive and concise manner, reflecting certain history and its evolution.
Common equipment in archaeology The first is the satellite positioning handset, which has a horizontal positioning accuracy of 5 to 10 meters. It is widely used in field archaeological surveys to determine the location and boundary of the site, and to collect spatial attribute information (latitude and longitude coordinates) of the site. In addition to positioning, navigation and recording of track, satellite positioning handsets also have electronic compass, speedometer, odometer, thermometer and other functions, and are small in size and easy to carry. The handheld adopts professional design, which is generally waterproof, shockproof, rich in functions, simple in operation, and can be connected with intelligent products such as personal computers, PDAs, and mobile phones for real-time data update.
However, satellite positioning handsets Can not meet the needs of detailed surveying and mapping work in archaeological excavation, can only rely on high-precision measurement satellite navigation equipment, so a carrier phase real-time differential technology based on satellite navigation system is applied to archaeology. It can provide centimeter-level (1~10 cm) three-dimensional positioning accuracy in real time. It has the characteristics of high positioning accuracy, convenient and flexible measurement, low requirements, high work efficiency, etc. It is fully reflected in the establishment of the three-dimensional model of the relics and the restoration of the original features of ancient remains. Its advantages.
