Since satellite positioning technology been used in forestry, many domestic experts and scholars are working on the application research of satellite positioning technology in forestry, all the application can be summarized as follows[1][2][3]:1) Investigation and management of forest resources, such as, plot investigation, forestry distribution detection, measurement of forest area, cutting area design and monitoring; 2) Forestry engineering survey; 3) Afforestation, including aerial seeding, forest classification and survey;4) Forest fire, including the fire position, area measurement and evaluation of forest fire; 5) Wile animal monitoring and protection; 6) Forest tourism and expeditions. 1.2 Problems Satellite positioning technology has been used to our forestry area, but there exist many problems in practical application, such as, poor signal, low positioning efficiency and low accuracy, so that part of the business which call for position can’t be done, especially in south of
Not only can we improve the precision of the forestry, but also to reduce unnecessary waste of time and material resources by this technology.
(10) (11) 3.3 Key Technologies If we want to combine ground positioning technology and satellite positioning technology, and apply it to forestry business, we should solve several primary technologies: ①Time Synchronize of satellite positioning and ground positioning.

Highway electrical and mechanical engineering networking operation management provides an important technical support for the implementation of the highway unimpeded, safety, high efficiency and the realization of the green highway traffic concept.
The equipments and products are of varying quality, so the stability and reliability of highway network electrical and mechanical engineering system meet a huge challenge.
In addition, the spread of the virus, hacker attacks and information falsified will cause the network system of highway electrical and mechanical engineering paralysis.
The system paralysis will not only influence the electrical and mechanical engineering operation, management and service quality, but also cause huge economic loss and reduce the ability of highway network service.

A digital approach is applied to aid NPD process, so as to assess design effect, which based on Computer Aid Design, Reverse Engineering (RE).
Product concept generation The concept design phase of new product development is the most important phase of NPD process, which is highly depend on the collaboration of marketing and engineering.
For massive volume product, it is hard to verify functional design or ergonomic performance, thus, a reverse engineering design technology (RE) is applied.
