Marimsys Mail
The Marimsys Mail service fulfills the demands of those who require confidential, reliable communication, with worldwide coverage. This may range from solutions oriented toward maritime fleets where distance is the primary reason for a satellite solution, to land mobiles moving in areas of spotty or incompatible cellular coverage. The system works by one computer transmitting e-mails to another with the Marimsys Mail software with the Marimsys Mail application located in the remote computer/s, Internet connected computers can use either the fixed version of Marimsys Mail, or Marimsys webmail.
Systems for mobile users can select between a computer - either fixed or laptop - dedicated e-mail terminals mounted directly on a positioning device, or any serial or USB port connected computing device.
The firstscreen shows the login window to access the Marimsys Mail software:
Enter the User ID and password to open Marimsys Mail.
When the "Draft New Message" button is selected, the following is displayed on the screen:
The addressee, which may be saved in the built-in address book, is then selected:
The subject of the message is then selected from a drop-down menu, or created particularly for the message to be sent:
The message is then written, which appears on the screen as it is typed. Finally the type of compression is to be used is selected:
When the message is sent to to a person using a standard text e-mail client, such as Outlook or Eudora, it must be sent in “Simple Text” so that it may be read by the addressee. If the communication is between users of Marimsys Mail, whether running the program on their machines, or with the Internet connected side using the web interface client for Marimsys mail, the two compression alternatives may be used.
Advantages and disadvantages of “6 bits Compression” and “Xzip Compression”:
when the message is written in the body of the message, use “6 bits Compression”, the message will be translated ALL CAPS and some symbols will not be included.
When there is a text file attachment “Xzip Compression” is preferred, however using Xzip for small messages (less than 300 characters or so) will increase the size of the message.
Caution, take care to not emit large normal or Gateway Mode e-mails, text messages of over 500 characters slow the delivery of ORBCOMM e-mails. The “Taximeter” is included as a tool to immediately inform users of the number of bytes in an outgoing e-mail. Use it to check the size of mails before transmitting, or if this system is to be used for passengers and crew who will be billed for their individual communications.
NOTE: While it is standard practice for Internet connected users to interchange MS Excel spreadsheets, this is not appropriate in a satellite data environment. The reason is that an Excel spreadsheet with one character inserted in one cell of the spreadsheet will result in a spreadsheet of approximately 14 kB. Try it yourself by creating a spreadsheet, insert one character in one cell and save the spreadsheet. Then check the size of the created file!
For this reason we use database type data transfers through the creation of customized applications for remote data collection to run on the remote side of the WAN. This data is then transferred over the ORBCOMM network using various “super compress” proprietary Marimsys algorithms. The data is precisely re-created in the Internet-connected server. These techniques can be used to effectively replicate WAN databases, from mobiles to fixed computers connected to the Internet.
The use of Marimsys Mail is familiar to any user of existing E-mail clients, simplifying and reducing the cost of start-ups. Our experience in data compression, transparent to the user, optimizes the use of satellite bandwidth, thereby lowering the cost per byte or kilobyte of data transferred. This more efficient use of radio spectrum, combined with the low cost of ORBCOMM data transfers creates the Marimsys ORBCOMM cost advantage.
