PST used to be a very small company specialising in communications technology - specifically radio communications. We have now been absorbed into the NRF-HMO organisation which provides our old and new clients with an increased scope of services, including geomagnetic experience, ionospheric and GPS expertise and training and conference services.

We have experience in managing, designing and implementing large static and mobile HF radio networks, mobile radio data networks, HF radio-, HF data modem- and Radio Data Terminal Equipment. Experience also includes design and production of computer equipment - add-in cards such as Voice Answering Cards, CT Phones, as well as turnkey network designs and installations. As far as software is concerned, in-house products include Ionospheric index (SSN, A-index and T-index) prediction software.

Products that are (so far) free on this web site include:

- Ionospheric information

- Warnings

- Indices usable with other ASAPS, WASAPS and IONCAP/ICEPAC HF software packages

- Warnings for satellite users

We can also provide, on request, the following services and products:

- Special HF link and area predictions

- Link analyses

- Radio Site planning
