Satellite based positioning relies on measuring distance between satellite and receivers. With known satellite position and measured distance between satellite and receiver, the coordinate of receiver can be calculated. However, the electromagnetic signals emitted by satellites are perturbed by atmosphere and clock errors, which degrade GNSS positioning accuracy. There are two types of positioning mode, one is point position and the other is relative position (see Fig 1). Point positioning includes standard point positioning (SPP) and precise point positioning (PPP). Their major difference is whether use the carrier phase observation. Relative positioning also includes two types: DGPS and RTK. Their difference is the latter one uses carrier phase observation as well. Relative positioning cancels most error sources in distance measurement by making difference between two receivers, so it is more simple and reliable, but it only measures relative position. In practice, the coordinate of
Loan Opportunity Offered By Mr, Benjamin That Save My Family From Financial Bondage {lfdsloans@lemeridianfds.com}
ReplyDeleteHello Everyone, I am Putri Adiratnaa single mom from Jakarta, I would like to share this great testimony on how I got a loan from Mr, Benjamin, when we were driven out of our home when I couldn't pay my bills anymore, After being scammed by various companies online and denied a loan from my bank and some other credit union I visited. My children were taken by the foster care, I was all alone in the street. The day i shamefully walked into an old school mate who introduced me to Daisy Maureen. At first I told her that I am not ready to take any risk of requesting a loan online anymore, but she assured me that I will receive my loan from them. On a second thought, due to my homelessness I had to take a trial and applied for the loan, luckily for me I received a loan of $80,000.00 from Mr, Benjamin. I'm happy I took the risk and applied for the loan. My kids have been given back to me and now I own a home and a business of my own. All thanks and gratitude goes to Le_Meridian Funding Service and for the help of Mr, Benjamin for giving me a meaning to life when i had lost all hope.
