I have an older GPS receiver that reports the wrong GPS week in the output data. The data is in binary format. I require an application that searches the output data for the week number and replaces the incorrect GPS week with the correct GPS week number by allowing me to input the correct week number. Attached is a PDF with the output information and some example files. Note that the GPS week number is reported in these files as 883 and should be 1907.

Hello. That looks like an interesting task. I could make a command line utility to parse files and correct the week number. ADDITION: According to your documents, GPS week is recorded in Groups 3, 106 and 107. The files attached do not contain such Groups and therefore I can't find week information in them. Could you please explain that? Best regards, Alexander.

Hi! My name is Konstantin. I'm skilled low-level developer with a lot of experience in reverse engineering and raw data formats handling. This is no so complex task, but it requires carefully binary data handling. I'm going to create simple demo and will sent it to you soon to prove my ability to solve this problem. Do you have a software to check correctness of week number after replacement? In which form you want to get the application - with normal GUI window or in form of command line tool? With best regards, Konstantin

Hey there, I'm really interested in working on this piece of software for you. I am a programmer with quite a few years of experience and also have a Masters Degree in Computer Science. I enjoy programming and also have a geospatial background. I've dealt with data similar to yours for both updating, reading, storing and visualizing. So I'm very interested in this project. I've read the ICD and looked at the GPS binary files to understand the format better. This is an application that I could develop for you no problem. I'm a C++/C# developer and I can develop software on both Windows and Linux. Let me know which operating system you are interested in using and I'll develop the software for that OS. I think that the best way to do this is to have a GUI where you can select a file and it will read in the data and let you know what the GPS date(s) is/are and allow you to set it to whatever it should be then write the binary file back out, either overwriting the file or writing a new one based on the user's choice. Being from the USA I have an advantage over other bidders as we share the same timezones, so you don't have to wait overnight to get answers or receive feedback, and I'm a native english speaker so there won't be any communication problems. Let me know how you'd like to proceed. I'm really looking forward to helping you out with this project.

Hello, I have had a quick look at the files and I am confident it is doable. What exactly do you need as the application? Do you need a specific language? Do you want a graphical user interface? Please contact me to discuss the details. Cheers, F.

Hello, I'm interested in this project really, but I want to get more information. For example what is the file's format (I hadn't read the whole content of the pdf file). I don't mean the extension, I mean the structure of the file. I would like to know if that information is inside the PDF file. On the other hand, I'm C++ experienced programmer under Qt library, about 4 years of experience with Qt. Also, I have experience with java applications. Best regards Edixon Vargas
