Founded in 1997, Objective Systems is a privately held company that develops and licenses software products that support international open system interconnection standards.

Our mission is the development of software that promotes interoperability between all types of systems. We believe this is best achieved by supporting open standards. Our core competency is the development of software to encode/decode binary message formats described in various standards with a particular focus on Abstract Syntax Notation One (ASN.1). These message types are described in standards documents from organizations such as the 3rd Generation Partnership Project (3GPP), Internet Engineering Task Force (IETF), European Telecommunications Standards Institute (ETSI), and others. The development and refinement of our products is an ongoing effort to produce software of the highest quality that provides optimum performance.


Our current portfolio of products includes the following:

ASN1C ASN.1 Compiler: a code generation tool that takes as input an ASN.1 specification and outputs code in different programming languages including C, C++, Java, and C#.

ASN1VE ASN.1 Viewer/Editor: a graphical user interface application for analyzing and editing ASN.1 encoded data.

XBinder XML Schema Compiler: a code generation tool that takes as input an XML Schema Definition (XSD) specification and outputs code to create and parse XML messages.

ASN2TXT: a command-line tool that translates ASN.1 binary encoded data into XML, JSON, and comma-separated-value (CSV) formats.


We offer training, custom software development, and extended support on all of our products.

Our products are in use on many different system types throughout the world, allowing devices of all types to communicate seamlessly.
